Let’s call a spade a spade. If Post could exist without the Fediverse, their VC backers would be over the moon.
It would mean that Post could subsist as a walled garden.
But just in the last week, Mastodon added 300,000 new accounts. Momentum for ActivityPub isn’t slowing down, it’s picking up.
At what point does the Fediverse become impossible to ignore?
It amuses me how the likes of Post acknowledge that decentralization is the future of social media but they’re not going to adopt it yet because they don’t know which protocol will “win”.
It doesn’t matter which protocol wins. It makes no difference if it’s ActivityPub or AT Protocol (Bluesky) or IMAP/SMTP.
What matters is that a social media message gets treated as a message.
Hence, interoperability.
ActivityPub isn’t perfect but it offers interoperability right now.
