It seems like Twitter should require 2fa for certain accounts, if not for the damage it could do to the US if Trump's account were compromised (personal endorsements, inventing crises like the fake Hawaiian missile crisis, scam links to solicit money, etc.), then for Twitter's reputation as a platform people can trust. If they didn't want to inconsistently enforce the rules for individuals, they could have a policy like any account with at least xx million followers must implement 2fa. What incentive do they have to not do something like this? Surely anyone with millions of followers isn't going to leave Twitter because of this requirement (new users might, hence only requiring it for accounts of a certain size)
