Last night Adam Mosseri, Head of Instagram, quitely announced the next step in the integration of Threads into the Fediverse. In addition to being able to follow Threads accounts from Fediverse/Mastodon accounts, we can now reply to and like Threads posts. Threads are taking a quiet, incremental approach to Federation, but seem genuinely commited. Why is this important? Because I believe that Meta as a whole is moving to an open systems approach, not because Mark Zuckerberg is a nice guy, but because he is smart enough to go open before he is forced to by regulators, (or broken up).
