People are gonna attack the source, I know. I don't put much stock in that defense.
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.)
