I get that point! But imagine "ancient youtube history videos" like "chocolate rain" were hosted on an old and unstable peertube node. I would find it sad that a decentralized infrastructure erased old and historic eras of the internet. I'm not saying this just defeats the whole fediverse, I just find it a point of concern, I'm sure if it is really a problem the developers and community will find approaches to mitigate it!

(Btw, I'm not yet well informed about all the caveats/tradeoffs/unwritten rules of lemmy/mastodon/peertube when it comes to data storage, so maybe what I'm saying just doesn't make sense at all, correct me if I'm wrong!!)
