It appears to me that the complaints in the video seem to go more towards the problems of license compatibility (or lack of backwards compatibility) between GPLv2 vs GPLv3 creating tons of problems with outside contributions to the kernel if the typical "or later" clause was used. Some of the other commenters here seem to stress the Tivoization clause, but it appears to me that that is not the real issue. Linus even says so, at one point when the guy asking the questions repeatedly tries to stress that point.
