I think that you have a point, however both the author and I disagree. The goal is not to have the entire Facebook (or Twitter, or whatever) population come on the Fediverse. From my point of view, a federated system which is still central, not FOSS and that monetizes the users is already in clear violation of basically everything I want to fediverse to be. What would be gaining from this? Just a raw number of users? I don’t think it is a worthy tradeoff.
