There is a strong rumour going round that some Fediverse developers and admins have held secret discussions with Meta/Facebook under NDAs. The Fediverse is supposed to be an alliance of open projects built by a broad grassroots base. Its devs/admins are not supposed to hold secret backroom discussions with people who have a horrific track record (https://www.theguardian.com/technology/2021/dec/06/rohingya-sue-facebook-myanmar-genocide-us-uk-legal-action-social-media-violence). Facebook/Meta is in effect a sociopathic corporation (https://www.buzzfeednews.com/article/ryanmac/growth-at-any-cost-top-facebook-executive-defended-data). Nothing good will come of talking to them.
