The point is that Akamai is probably correct that all Linode really needs to change to be seen as viable by large corporations is the marketing. Its incredibly dumb that the world works like that even at the scale of large corporations that you would think would care less about being marketed to, but my experience has been the opposite / being tickled by marketing is even more important for big corporations.
It should also be noted that the people who choose infrastructure vendors are rarely the actual sysadmins in charge of the infrastructure. These kinds of decisions are standardized across large organizations (sysadmins would never be able to agree on something like that let's be honest) and the choices tend to be made by people who haven't set up a new server in a decade, (if they've ever done so then they are more technical than most in charge of IT purchasing).
Think like: a sporting goods company buying a tire company, not to make tires, but because they want to sell their existing customers rubber balls to go with their knee pads and stickball sticks; and the tire company happens to have a good rubber-goods supply chain that can be repurposed to do that.
Akamai doesn't want to get into the VPS business. They want to repurpose Linode's systems to extend their "cloud-services integrated solution provider" solution portfolio. Remember "IBM SoftLayer"? Akamai wants to be IBM, and so they need a SoftLayer of their own.
Akamai doesn't want you as a customer if you're not spending millions a year. It's not worth their time.
It should take few brain cells to understand business is driven by return on investment and not "most burgers served"
