Rallies? Trump had like a hundred million Twitter followers. The total number of people who even can go to a rally is like 30,000 at extreme scale. Even if he had a massive rally daily (impossible) with no repeat visitors (absurd) in a year he still wouldn't get to 1/10 of the people he could reach via Twitter. And he'd be able to reach them each once. Plus he'd never get any casuals or outsiders like me - people who go to rallies are already committed. Rallies are not a substitute for the entire edifice of modern social media.
A hundred million twitter followers isn't worthless or meaningless. If someone you liked was ever silenced like that, you'd be up in arms and rightly so.
