By extension, this is why I don't think defederating with Meta is an effective strategy. Like gourmet burger restaurants refusing to be on the same block as McDonalds.
Meta will get the big names as they exit Twitter, and become borderline necessary to federate with-- assuming updates from years of state, artists, activists, etc are of any interest to people considering your instance.
This is inevitable. I think the only discussion is how we have a vibrant enough community that EEE becomes less viable.
It's something we failed to do with email. I suspect the answer is approximate to far easier instance hosting, to increase the number of instances and make a federation whitelist unviable for Meta
