There has been a lot of work done to create decentralized freedom-respecting services in recent years. (Lemmy is obviously one of these). That being said video hosting seems to be one of the hardest things to replace with a decentralized solution since video files are so large and therefore expensive to host. The only serious attempt at a decentralized youtube replacement I’ve heard of is LBRY, but I have a general skepticism about blockchain-based businesses, and the available technical information released by the company behind LBRY does not alleviate those concerns. I don’t really have any solutions to this issue, I currently just use youtube with sandboxing, but this is obviously not a great situation. Curious about everyone else’s thoughts.
There is of course PeerTube, a fediverse alternative for video sharing: https://joinpeertube.org/
It’s still hard to get around youtube as most content is there, what I do to at least not have to visit the site (nor needing an account there), is to subscribe to the RSS feeds by channel in an RSS reader (like newsboat), and then just watch the videos with via a player like mpv, works perfectly.
