Like how Apple, Google, Intel, Nvidia etc. are exploiting the LLVM project? IMO, the need for GPL style restrictive licences isn't backed up by facts; more open licences encourage commercial use and open development.
There's a game I own that I'm only able to play on my computer because its developer accidentally used a GPLed audio library, and found their best course was to GPL the game engine. Internet volunteers then ported that engine to other platforms. So as an end user the GPL really has made things better for me than a BSD-style license would.
