I don’t get why the author seems to think that Linux is governed by GPLv3 — in fact, Linus has explicitly said he’s not going to use the new license, and that he’ll continue working with GPLv2. (Not to mention that most component applications, et. al., have multiple developers/contributors, and all of them would have to agree in order to modify the license.)
Yeah, I know. But I think his main point is valid—MS is just throwing money away with no tangible return. They cannot, realistically, sue anyone over the supposed patent violations, which means the patent “deals” made with Novell and others are just hot air.
