A few pointers...
abjayme...
Read the MS-PL license.
"(B) If you bring a patent claim against any contributor over patents that you claim are infringed by the software, your patent license from such contributor to the software ends automatically."
Doesn't the GPL have the same kind of philiosophy behind it, in fact doesn't GPLv3 state that outright?
And the anonymous comment...
What choice do you have in MS:
1) Do you have a choice of an Intel OS before?
Ummm... Linux? Mac OSX? OpenBSD? FreeBSD? NetBSD?
2) Were people given good judgment when MSOffice comes bundled in the OS?
Err.. MS Office is not and AFAIK never has been bundled in with the OS. Wordpad has, but not MS Office... and what is Open Office? Star Office? Ability Office? (and that's only on Windows)
3) Were people given good judgment when IE comes bundled in the OS?
Which they can then use to download Firefox, Opera or Safari?
4) Were people given good judgment when MS announce they don't want Vista
virtualized on top of their competitor OS?
Where do you get that information? And I've already seen Vista virtualised on a competitor OS (MacOSX using Parallels) Why would Microsoft care anyway? Whether it's used directly on a PC or virtualised, it's still a sale of Windows Vista.
