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".
Elon Musk's focus is on people who are paying for Twitter.
Who are Twitter's "high value customers"? Advertisers.
What advertisers want is a better advertising system.
They don't give a damn about decentralized social media because there's no centralized system that feeds people ads. Mastodon can't help them.
Twitter advertisers are like folks in the 19th century who are demanding a faster horse.
Guess what? The proverbial horse will soon be put to pasture.
