Nope. FOSS doesn't have the marketing or rapid development of centralized services. We stand out on longevity and stability over night however. Who knows how many days Twitter has to keep their lights on, and then the whole thing is dead. ActivityPub has no central point of failure, so it'd only die if every single dev lost interest. Though we definitely have a lot of problems we need to figure out, and our development is incredibly slow compared to theirs.
