This blog post by Ploum, who was part of the original XMPP efforts long ago, describes how Google killed one great federated service, which shows why the Fediverse must not give Meta the chance
My synopsis is that if any big corporations joined the Fediverse they would fracture it.
I’m not so sure. Facebook has an onion version that runs on the tor network. Big tech dominates the clear web but there’s plenty of room for everyone else.
Ultimately you have user types. In a few more months, LemmyVerse could have a couple of million active users.
I’d bet the vast majority would scoff at a fediverse version of Facebook. It’s just a different crowd - not unlike the tor network where Facebook (probably, maybe?) exists in nmae only.
