Surely GPL applies ?

How is that possible ? Surely if they modify the GPL'ed linux kernel then the GPL mandates that they release the modified source also under GPL ?

On the general issue, it seems pretty clear that Linux development has spread off over a wide range of different machines and different apps in ways which go far beyond Linus's personal concerns. If there's an issue at all, it would only be in the way Linus chooses to prioritize the merging and releasing of various kinds of changes. And while that may not be optimal in some theoretical sense, it seems to happen faster than progress in any of the mainstream proprietary OS's.
