Mastodon has fallen pray to its popularity and now is (maybe inadvertently) abusing it's position to keep the quality of Fediverse applications low. Its implementation of the common ActivityPub specification is abysmal and sadly the developers always have different priorities.

I wish at least one of their team was more focused into improving their ActivityPub code and try to act like a good community member instead of the preserving the status quo, which is: being a microblogging platform before being a fediverse platform.
