I think the wording is a bit misleading, too. Those users didn't actively commit to #FediPact. They just happen to use an instance where the admins decided to block Meta. Deliberate or not, it is indirect from the user's perspective.
And my opinion is: The whole #FediPact is very unbalanced. While we do care, we also have to remind ourselves that Meta probably don't care at all about -for example- the 40.000 users on Lemmy.
