The problem is not really lack of platform, it's that Google cares all about its employees and nothing about its customers.
The nature of business is that you sell something to your customers. If you don't listen to what they want, you will eventually be replaced by someone else who does.
Google has been phenomenally successful because it built a better search engine and has kept improving it. That is the ONLY thing at which it has been successful AS A BUSINESS. It has been reasonably successful in some other endeavors, such as Android, but it has yet to make any significant revenue at that, and may never do so.
But Google shows no interest in even trying to find out what its customers want. The lack of adjustable font sizes in Chrome that Yegge mentions is typical of that. A more critical example is Google's refusal to accept that, for many people, an app that is not available offline is not functional, because only in Silicon Valley is the Internet truly 24/7/365, and because if your data only exists on Google's servers, you have no real control over it. See
this article by James Falllows for an example of what that means.
Jeff Bezos may be as awful a boss as Yegge says (although one should take an ex-employee's gripes with a grain of salt), but he is all about satisfying the customer, not his staff, and that is why Amazon may be around long after Google, unless someone at Google eventually gets it.
