On Android it’s simple, patched with YouTube ReVanced Manager

I did, but after the 3 videos, it’s no longer a pop-up that can be removed, it doesn’t load the video at all. Annoying as fuck. I use incognito mode as a workaround currently.

I feel like for decentralized identity maybe a page could be taken out of Blockchain. Ethereum ledger is duplicated in its entirety on every host, and there are L2s that help spread the load but roll up to the L1. If identity could be attached to something like that, each person has a key to identify themselves. Identity I think would be best separated from all content related to the identity, the user could choose a server to host that data, as well as back it up with like a shared user data backup agreement between a few servers in case one dies. It’d be very similar to raid but the data only needs to be on 2-3 servers. I suppose community data could be the same. I can envision when a new server joins the federation, it could be auto assigned to share with 2-3 similarly sized communities with algorithms making sure there aren’t any closed groups of sharing (a->b&c, b->a&c, c->a&b) wouldn’t ever want that. They all seems to be the most reasonable solution in my head.
