@gamey TBH, I personally do not much care about that one (unless it means to get the data OUT of their greedy hands to get them IN to free, libre, transparent services). And I haven't yet heard of a libre SN where you could import your DATA (profile, metadata yes, but all your messages?)
The other part I rather do NOT want. My messages going TO some MAGMA service, for inter-operability? No, thanks 😉
@IzzyOnDroid In case of the messages the final goal seems to be something similar to Matrix (some people from Matrix, XMPP and Neochat (KDE Matrix client)) where invited to a meeting next to some people big tech/silicon valley so I assume the social media interoperability would have been comparable to Activitypub and don't really see what exactly you worry about tbh. I can't recall who wrote about it but there is a great post about that meeting on open collective!
