If the people who produce videos don’t stop, there isn’t much of an alternative other than abstinence.
At which point, what’s the benefit over using a mirror like invidious which gives you your video, uses up resources of the people you don’t like, and doesn’t harvest your data?
I wouldn’t use the actual YouTube site, or software clients. But open source mirror/alt clients like invidious, yt-dlp, or newpipe seem like a workable alternative.
Until people who make videos move the fuck over, most of my subscriptions in newpipe will continue to be YouTube accounts, and not channels hosted on a peertube instance.
Luckily newpipe works with both… For now.
