Can somebody explain me exactly how defederating them would give us a different outcome?

I’m genuinely curious.

Meta couldn’t give less fucks about 100k users on lemmy, they are targeting people that isn’t and will never use nor understand what the fediverse is.

You keep them out, good. They don’t care, they just want to fill their own bucket with stuff that is outside anyway

Twitter people going to threads is completely independent from anything in the fediverse. Those people won’t even notice any difference if they are federated or not.

They are in for the brand and the fomo, not the content
