I added the izzydroid repo and I don't know if the repo just isn't working or what, but there is no newer version listed for me.

Indeed, it's an answer to the problem of people's right to organise and govern their own communities. It's not perfect since federation is literally interconnected (to various degrees) centralised instances, with each one controlled by one or a select few people that the community trusts, but it's better than commercial platforms and closed protocols.

I think this is an important point to consider. For a long time, I kept thinking that the fediverse was going to be the answer to the problem of keeping separate accounts on every site (because most places are isolated/walled-in networks). It took me years to accept that "one account everywhere" isn't what the federation model is about.

I wish there was such a thing, but that's going to require portable identities/user accounts, and I don't know why but that seems to be progressing at a snail's pace with a bunch of stagnated RFCs everywhere (but please let me know if there is progress happening somewhere, I may be out of the loop). Once we have that, it'll make the fediverse a lot more convenient, since then you should be able to log in to other instances with the same account.

And there is a nice graphical frontend for it too: Vorta
