My concern is less Suckerburg as much as Meta's corporate history. My expectation is that they'll try to use this to conquer and destroy Lemmy.

Ideologically, I find more fault in inviting meta to the playground than locking them out. They are the very definition of an evil corporation and no good can come of it.

I thought the whole ideology of the fediverse was to get away from corporationl influence. So I'd say this is very much true to the ideology as well.

Yup.

Exactly, there's an exception to every rule.

I saw someone in another discussion say it perfectly: they put the meta back in metastatic!
