Data gained through integration of an instance is far more than what’s gained in scraping. The data gained through federation will no doubt increase as Meta adds new features that require more data in order to federate with them. They have over a decade of evidence showing us they’re evil and have no respect for privacy or people. I do not understand your logic in saying it’s okay to federate, it’s like watching somebody defend an abusive partner. They’ve hurt you and communities in the past, stop giving them more rope. The devil does not need an advocate.
