Andy Bechtolscheim says:

It’s really hard to add value to Windows. Whatever you add, Microsoft is going to take away from you.

Linux has opportunities. There are many ways to add value. There are lots of things Sun customers expect that are missing from Linux

The first two sentences are relatively common wisdom. The last sentence, maybe. But are the middle sentences right? There is an implicit assumption that you can add things to Linux without some big bully taking it away from you – or at least making the attempt.
