David DeJean from InfoWorld writes on GPLv3:

What is clear to me, though, is that by insisting on making the GPLv3 a weapon of war, Richard Stallman and his Free Software Foundation have thoroughly alienated Linus Torvalds and his Linux crew, and a GPLv2/GPLv3 split seems likely. I don't see how the open source movement continues if it can't present a united front.

The people and companies that use Linux have enough trouble already trying to walk the line between open source and commercial software. Adding a GPLv2-vs-GPLv3 layer will make it an order of magnitude tougher.

The more ideological provisions of the GPLv3, like those that target Microsoft and "tivoization" of hardware, may have the unintended side effect of marginalizing, not enhancing, the GPL and the open source model.

Not only has the FOSS movement held itself back by blaming software patents rather than addressing its shortcomings, the FOSS movement has failed to deter the single most destructive factor that may topple it- the Free Software Foundation.
