I might be misunderstanding something about atproto, but isn't it always possible to export data from bluesky because all it takes is reading your data, which is done by any app interacting with your pds anyway? If they block that, they're blocking atproto functionality entirely, no?

Keep in mind, twitter got rid of their API. Google got rid of XMPP federation. Bluesky breaking or defederating atproto wouldn't impact most users, so they'd probably get less outcry than those examples.

Yes, there are backup services that can help so you cannot be locked away from your data too.
