One thing I will say about decentralized social media is that we don't know where it will end up.
For example, when the first smartphones came out, they came with physical QWERTY keyboards. Now they're input with touchscreens.
Right now, decentralized social networks look like Twitter duplicated across multiple servers. But it will evolve into something substantially different in time.
The problem with chasing after "high value customers" is that they know what they want.
Concurrently, they don't know what hasn't been invented yet -- they're not considering future innovations.
Back in the 19th century, if you asked someone what they wanted in terms of better transportation, most of them would have said "a faster horse".
