What thunder? Mastodon has had nearly a decade to go mainstream and it's still mostly tech enthusiasts explaining to their friends what an 'instance' is.
ActivityPub is fine if you enjoy your identity being held hostage by whatever random server admin decides to keep the lights on. Want to move servers? Hope you're cool with losing your followers. Want real account portability? Too bad. Want scalable search and flexible moderation? Also too bad.
ATproto wasn't built to compete with Mastodon out of pettiness, it was built because ActivityPub fundamentally cannot accomplish the task that ATProto/Bluesky is aiming for: a decentralized social network that isn't a cumbersome pain in the ass to use.
This isn’t Mastodon so a “Bluesky server” isn’t a thing.
Mastodon is shaped like email so you have “servers” sending messages to each other.
Atproto is shaped more like RSS with aggregation. Everyone posts data to their hosting (which anyone could move at any time), and apps like Bluesky aggregate data from everyone’s hosting.
So a concept like “Bluesky server” is nonsensical. What you have is “atproto hosting” (which can be provided by Bluesky, by other communities, by other companies, or can be self-hosted — it’s all open source and you can even implement your own) and “Bluesky app” (of which there’s only one — but there are forks like Blacksky which fork the entire stack including the server). There also “other atproto apps” like https://leaflet.pub, https://tangled.org, etc, which have nothing to do with Bluesky.
I made my account on a server that a personal friend span up. Said friend deleted it on a whim after a few months after not using it much, not really aware of the implications. Personal connection was not the issue here, ownership of my digital identity was.
