Bleh, yeah I really hate to side with Google, especially when releasing this documentation benefits users and hiding it benefits Google.
It seems weird for this new license to be legally binding. If someone committed this to the wrong repo, and that person didn't have legal authority over the original content, then how can they have legally relicensed it? I would think that it would be necessary for them to have ownership of the content in the first place.
This may not work out the way I want it to, but I'm actually a little excited about these tech companies making a bunch of anti-consumer decisions all at once. So many mainstream users will be looking for alternatives, and it's going to provide a great opportunity for non-profit open source projects. It's already happening with the fediverse suddenly becoming a viable place for discussion in the last 1.5 years. After Windows Recall was announced, I've seen more people talking about switching to Linux than ever before. Part of me can't wait for unskippable Youtube ads.
