The issue is not the strawman you put up, where you mention it is scary to the leaders that people are getting access to information and making choices. The issue is that people are riling up large groups of people based on lies and making deadly threats (like Trump's "beat up the people in the crowd who are protesting"), leading to threats, attacks on govt - these attacks are based on absolute lies, and deadly threats of violence and some of them end up happening. Also your broad arguments about "authoritarian regimes did things, so they are bad". It's the specifics that matter. Dictators who controlled everything in say Russia also controlled the production of milk, that doesn't mean milk deliveries are authoritarian and bad.

Everyone is not on the same level now. Some are willing to make incredibly outlandish claims about stolen elections, and make personal threats to others, they are fine with that and they have enough power to make it hard to stop them or counter their reach.
