Most people have never heard of Lemmy or the Fediverse and were not invested one iota in the API Fiasco because they don't know what API stands for and they normally use the official mobile app.
So the Fediverse has an uphill battle. For the vast majority of Reddit users, Reddit still does everything they need it to and there's no great call to migrate over. People that are only peripherally aware of the Fediverse may also think it has something to do with blockchain technology. The technological savviness divide grows larger by the minute.
