@polotek all other things aside, what matters isn’t the technical architecture but the social norms. Mastodon is full of folks who are extremists (by modern tech standards) about consent, and who want defaults to be opt-in for nearly everything. In particular, Bluesky has both a different economic model and a different privacy model than the rest of the fediverse, so it makes sense to start with consent because the decision to federate is irrevocable in terms of data leakage.
