Someone is wrong lol. NFL, for example, cannot do anything outside of Twitter at this time. They are apparently working on it, but it’s gotta be implemented league-wide, so it’s taking some time. Idk if they’re even trying to get onto Mastodon, last I heard it was just Bluesky.

This is a large org with hundreds of millions of fans, with no presence on Fediverse really. I’m sure there are mirror accounts, but none are official.
