I think that article gets most of it. There's some MSFT narrative that comes up here a lot where people say Ballmer was doing great and Nadella just continued his plans, I don't buy it.
MSFT had a lot of strategic failures as well as product failures under Ballmer. Nadella shifted strategy and made them a serious competitor again.
They were making money hand over fist, massive growth in revenues almost ever year under Ballmer. [1]
Which part of that massive money train is 'not serious competitor'?

Revenue growth isn't the whole story. If you're extracting rents from legacy locked-in products or enterprise deals that doesn't necessarily mean you're a competitor on the new paradigms (phone, cloud, web).
At the time Windows phone was a failure and they missed that entire platform because of Ballmer (there's hints of your argument in this video, "we're making money with windows mobile"): https://www.youtube.com/watch?v=eywi0h_Y5_U
MSFT cloud wasn't doing well and was overly focused on .NET
They were too focused on Windows rather than recognizing the strategic value they could provide outside of it: https://stratechery.com/2018/the-end-of-windows/
Today I'd make a similar argument for Intel. Intel doubled down on old style fabs and is not competitive with TSMC. They failed to compete on mobile. They're ignoring the end of x86 and mocking Apple: https://hardware.slashdot.org/story/21/02/08/2221233/intel-b...
Increasing revenue is a good sign, but it matters how. If you're making short-term decisions to extract money from legacy stuff at the expense of new products - that's bad for your long-term future. It can take a while to catch up to you, but it eventually will. Then you'll just limp a long as a dinosaur that makes enough money to survive but nobody really wants to work there and you're done doing interesting projects. That's basically what I mean by irrelevant.
Ballmer didn't 'make money from extracting rents and screw everything else up'.
Ballmer entrenched and expanded MS core products i.e. Office to the Cloud and along with that massively expanded revenues, which continue to this day, long after his departure, with no signs of slowing down.
He completely screwed up Search and Mobile, but those were risky new things, that's to be expected. Frankly he should have had 1 of 2 ...
But he also established XBox and Cloud; the former is a very successful play into a very difficult space (though maybe not as nice in terms of profits) - remember, Google just completely failed at this. The later, is now a hugely successful and growing business, and frankly, over the long haul has a shot at actually going toe-to-toe with Amazon.
Microsoft has 10's of thousands of sales people and direct access to every single CTO in the world if companies with > 1000 emoloyees. Much the same way they are going to stomp Slack, they have that kind of advantage (though not the same leverage) against AWS. Point being - he started a massive business.
Azure now has revenues of more than Windows did when Ballmer started, and it's growing by 40% YoY.
So yes 'revenue' is not the 'whole story' if someone is bilking a cache cow and running everything else into the ground ... but that's now what happened.
Ballmer 'grew and entrenched the cash cows' and made some other huge bets, some of them working out to the point where they are now also, big growing foundational aspects of the business.
'The Market' took a long time to recognize this, but all the historical sales numbers are there for everyone to see.
I believe that once Analysts realized that 1) Windows and Office is 'here to stay' and 2) due to AWS, Azure is going to be huge ... that they revised their view on MSFT from a 'old company' to a 'well run growth company'.
Satya seems great and has made some good moves, but nothing of the magnitude that Ballmer did. At least not yet.
Satya's changes have been positive but most of the money he is making is due to Gates + Ballmer.
I think he's good but we'll have to wait to see the full picture.
Then it should be easy to say which green-field projects Nadella launched then. I can't think of any, but I'm open to learning.
