"I can host my own single user server for $6/month".
Right. That's nice, but that comes with other limitations. Like, you are seeing someone's post and the replies that you see might be different from the replies that people from other server see.
This would not happen on ATProto because the way it works is different. And that's why, coming back to my first reply, that I think there's room for both and we don't need to root for one to win over another.
If you want to host 13 million people of course this will have a huge cost. But you can if you have the resources for it. As here, if you have a big server you will have big costs. Also, the ATProto allows for people to host only part of the network, so different parts of it could be maintained by different people, different from ActivityPub.
Like in this image: each part of the infrastructure could have a different provider (or multiple ones).
The difference from those to Bluesky, is that Bluesky is not only a social media but a steward for this open protocol called ATProto (as Mastodon is for ActivityPub).
In case Bluesky turns out bad in the future, anyone can host the infrastructure themselves, and people can move their whole existing data to this other provider (obviously this is easier said than done, but it's possible).
@molly0xfff @stefan why would we want some to win over the other? Their premises are different. I think there's room for both.
