The market will bear what the market will bear.They def did what we could see is a switch to the high walled garden like apple for all tech companies. Microsoft is doing it with windows 8 I can see more companies following the tend of limiting open source from now on.
If open source is a good idea, then it will survive.
If not, then it deserves to die.
That said, other then Linux, we don't have any open source today in the environment. Each has some proprietary / exclusive portions of it.
