I'm usually on Microsoft's side, but that's only because they're a reality. Condemning Redmond, fighting against the proliferation of the Windows scourge, all that stuff just seems like fighting city hall. I'll tilt at windmills in my personal life, but when I'm working, I just want to get the job done. Most of the time, that involves Windows, so spending umpteen precious hours trying to figure out a way to do the same thing without Windows simply because I dislike big, rich companies seems like a waste of time for me and money for my clients.
That said, this intellectual property thing is juicy, gourmet-class FUD. Microsoft can't enforce some kind of class-action fee structure on open source software — not going to happen. And if what the Linux guys say is true — that Microsoft inadvertently made itself subject to the GPLv3 license by distributing Enterprise Suse as part of the Microsoft/Novell alliance — the open source world isn't suddenly going to get access to all the secret bits and bytes behind the Windows curtain.
The lawyers are going to have a payday. I'm going to get ammo for a whole bunch of literary zingers. And in the end, it'll be business as usual for both the Penguin and the rainy Northwest.
