It’s important to know know that by this google still can’t run their own fingerprinting scripts or fingerprinting stylesheets, nor set cookies, so while not ideal, it’s not that bad.

I would suggest that (except when you watch something more private) until this gets somewhat more sorted, turning off video proxying is probably not a huge tradeoff. Also don’t forget that FreeTube and NewPipe don’t do proxying (FT can be set to do that, though)
