iirc, atprotocol was made to bring some features of mainstream social media to the fediverse that activitypub maintainer have said they won’t be adding. They explain other reasons in their faq
It doesn’t say there’s any limit on their github
In theory, bluesky can federate with other apps but it is currently the only one using their protocol, bluesky servers can federate with each other and when a new project using atprotocol appears it will probably be able to federate with that
I’d hope it’s carefulness but it doesn’t seem like it. Facebook should want to destroy fediverse instances (from a business point of view), they are supposed to be a monopoly and the fediverse is their biggest competitor.
It took around a year for a solo dev (and a couple contributors) to develop a fully federated platform. Why is it taking one of the largest companies on the planet this long to make such tiny changes that are useless anyway.
And why are they releasing it like this instead of releasing everything at once?
I also use boost, everything about it seems to work apart from spoiler tags (think because the app still uses reddit’s format instead of lemmy’s).
According to this blog post, they are currently limited to 10 accounts, so not many open servers, but you can host your own.
This is an old blog post, though, so the limit might have been lifted
