Mandatory shoutout to Invidious: https://invidious.io https://github.com/iv-org/invidious An accessible interface to YouTube content without tracking, using a decentralized network of community-run instances that scrape, rather than API-call, site data. [EDIT] Also Yattee doing the Lord's work: https://github.com/yattee/yattee Privacy oriented video player for iOS, tvOS and macOS with Invidious support.
At some point I will set up a yt-dlp thing to download the videos I want because the public instance invidious experience recently has not been great. I could also try a self-hosted invidious.
Something interesting is considering the privacy benefits of watching the content on a privacy frontend while sitll talking directly to youtube. Does it prevent the fingerprinting? Does it improve your privacy significantly?
I imagine the shared frontend proxy approach is best for privacy, but is not reliable currently.
photon-reddit.com has been a gamechanger for one specific feature—it lets you recover deleted comments and posts. But, I have found it less reliable than redlib.
