I think it’s been around like 10+ years? But it’s very obscure really, though a lot of ppl moved over after Elon took over Twitter.
I know it’s based on a standard called ActivityPub. There’s no corporation directly involved or funding it, no. There’s three main versions of fedi software made by different ppl, but I’m not sure who started it all.
It was created by some kind of open source foundation over 5 years ago, it's based on a different protocol call OStatus that's much older. But from what I understand it's abandonware. I don't think the official ActivityPub site is even up anymore, The Fedi is ironically built on a dead standard even though it's the biggest distributed microblogging network around.
