The history of Facebook (there I said it) and the EEE example MS already provided us years ago (as referenced by @HeartyBeast ) does not incline me to believe in their good faith. If Meta has proven one thing over and over and over, it’s that their interests will always lie in harvesting of user data to enrich themselves, and that any restraint on their part will be that which is legislatively forced.

Let the Fediverse grow on its own. It’s not a race. And it’s surely not a race best won by letting the wolf in through the front door.

The day we federate with Meta is the day I find the fediverse instances that refuse to do so, and take my account there.

Edit: Blog post on this topic that goes into some detail about historical precedent and etc.
