Related to this, today I saw someone on the birdsite say (paraphrased) "most people don't want mastodon instead of Twitter because they just want to know that what's posted by the BBC is from the BBC" in among a bunch of stuff about how decentralization isn't that important, actually and like...
I'd rather know it came from the BBC because it came from the BBC's domain name than because some rando corp got thrust into the position of deciding who is and isn't real. Decentralization is the solution to this problem, if anything.
