It seems like a no-lose for aspiring oligarchs, buying a social media platform with a large enough left and/or youth user base:

1. muck with the algorithm until what remains is a new right-wing echo chamber; or
2. accidentally sink the whole platform, but at least you wrecked a popular place for left-wing messaging; or
3. somehow not meaningfully change the status quo, and end up with loads of user data and ad revenue.
