In the e-mail some people have sent me a link to this. Pointing in particular at this part:
It seems from my reading of the daily press that the Free Software Foundation, Presided Over by Richard Stallman and being legally represented by Eben Mogen, is taking the position that the terms of the GPL (GNU Public License) define MS as a distributor of Linux, and as such, the patent protections it agreed to previously with Novell under GPL2 now apply to all Linux users.
You read that well. In terms of the GPL, Microsoft is a Linux distributer. This, once again, shows that the GPL is one crazy license written by crazy people, there is no reason to be worried. Microsoft is not seriously involving with open source. It is infiltrating and killing it from the inside.
