Everything else in the post rests on this, and I'm not sure that its true. Do you have research or statistics to support this claim?
I'm curious what these industries are. Oil? Investment funds? Pharmaceuticals?
I'm thinking that there are a few industries where commoditization has not happened over the last few hundred years. Of these, I'm curious how many of the industries commoditization could happen in, but has not, and how many (for some reason) are strongly resistant to commoditization.
Moreover, commoditization doesn't happen immediately as there may be industries who disrupt existing solutions (as SaaS has done to Enterprise Software) but aren't yet fully established themselves (or in particular verticals of the new industry) and these can have time to evolve before commoditizing. Having said that, it's always better to commoditize yourself before customers (and potential customers) perceive you as a commodity. The reason for is that it becomes much harder to evolve into a preferred partner/problem service where you can make much higher profit margins during this stage as you are being compared on price & not your defensible value add.
The simpler the Saas service, and the lower cost of switching, the more competition and commoditization that may go on. But this article is talking specifically about Saas replacing enterprise software. Software is sticky, and some software is very sticky because it is mission critical, highly integrated into the business workflows, and/or there is significant user interaction.
For example, if a company has 500 sales people all happily using salesforce.com, why would a CIO disrupt everyone's work to switch to a cheaper but different product? The cost of salesforce.com is not a significant cost to the business, but the cost of disrupting people's productivity swamps any savings you might from switching to a cheaper service.
This is similar to someone telling a company to drop MS Office because OpenOffice or GoogleDocs have equivalent "good enough" functionality and are free. There is no 'commodity' version of MS Office which looks and behaves exactly like MS Office but just with a lower price.
I do however agree with you about the switching costs, Salesforce actually use this as part of their lock-in & differentiator in that they have got their users to associate them with CRM - their stock ticker is it etc - this they become product evangelists for them. As a result, there is a network effect built around Salesforce which has helped them create a lock-in.
However, that sill does not mean users won't switch (look at the new http://www.moz.com it isn't a coincidence that the UI looks like Google Analytics - that is one such example of how to "break" the lock-in). Moreover if a customer is offered a Salesforce alternative for 20% of the cost & it does exactly what Salesforce can do (as well as having a similar UI) that becomes a serious incentive for a business to switch - after all most of the decisions are made by the CIO etc who doesn't necessarily use the product day-to-day.
Finally to address your point about there being no commodity version of MS Office the problem is, is that no alternative has actually managed to provide a product to a similar level - Excel is by far the most superior spreadsheet product on the marketplace.
But you are right that the switching costs trump the costs.
For the switch to make sense, I think you need to offer 4x the value to make up for the switching costs. So that can be some combination of cost savings and better functionality.
Salesforce.com is a perfect demonstration of the power of the network effect - the product, in my opinion, has really isn't that great. Yes, it's fairly flexible but feels very dated and the reporting is slow and cumbersome. In theory, their system should be relatively easy to disrupt, but none of the competitors can match the number and level of integrations out there.
A good article about the economics of SaaS: http://pandodaily.com/2013/06/15/what-the-data-reveals-about...
You could argue that Wal-mart is a commodity too. It's just stores and the same stuff as K-mart and 7-11. But it crushes them. There's room for both Wal-mart and Tiffany's just like there's room for a SaaS for your billing system, and Accenture to build a custom one.
Whereas SaaS currently tries to say "this is the solution" it needs to be flipped to focusing on actual customer pain points (since the current solution may not actually meet their needs) which you can the re-create a slightly new solution which becomes your unique selling point and defensible base (which is why it's important to go beyond competing on features). The reason I'm arguing this point is because, SaaS is becoming commodified in that they they winning SaaS in the SMB space start getting pulled upstream to the enterprise market where their margins become much greater and SaaS becomes their method to provide you with the product than their actual business model.
Your examples actually reaffirm my point - Walmart has added value by offering "everything under one roof" so instead of going to 10-20 store you just go to the 1. Their value is convenience alongside this they also compete on price to protect their market from disruption and ensure they're the dominant player (its a 3 pronged attack which Amazon is replicating on the web). On the other hand Tiffany's offers you a more personal experience than a Walmart does (in my opinion) which is their comparitve value-add alongside their actual products.
And at the same time, all these services are, as the article points out, becoming commodified. Thus, recognizing that they really can't make money in the SMB market with such low switching costs, they decide to move to the enterprise market and thus the whole economics of SaaS are blown up, and they look very much like a traditional enterprise software business - and SaaS becomes a delivery methodology rather than business model.

I don't follow. Okay so I find a selling point but what exactly makes it defensible or 'unique'?
SaaS currently tries to say "this is the solution" and as I was saying in the post it needs to be flipped to focus on actual customer pain points (since the current solution may not actually meet their needs) which you can the re-create a slightly new solution which becomes your unique selling point and defensible base (which is why it's important to go beyond competing on features). Essentially SaaS is becoming the method to provide the customer with the product rather than the actual business model and if your SaaS works with your customers & solves a key problem for them beyond "hey pay us X for these features" you will become a preferred partner who is solving a key problem which is critical to the success of your customers
Are you basically saying that in addition to features, you need to provide service because that is what makes you defensible? It is just not very clear how a slightly new solution is inherently defensible. You could make your product offer a slightly new solution by improving a feature. I'm guessing you'd argue that isn't defensible. So what concrete characteristics make it defensible? May be you are hinting at marketing/branding - once you have a brand/mindshare, people are less likely to switch to commoditized alternatives(ie. Tylenol).
You should start with something unique and keep making unique things that delight the people who are willing to pay for those things.
It's not a complicated idea, but it takes focus and time to really get to know your customers and their needs.
I do however agree with you that, you should always try to offer something unique (as this is the USP and where you can make higher profit margins) and that it can sometimes take time to achieve this. However, SaaS is not revolutionary and it can be copied by anyone and some of them may have a nice user interface and/or great product functionality but it is not revolutionary aka a commodity - which as I mentioned in the post is a death spiral as it focuses on competing on price.
