That's not what's dangerous.
Instead, dangerous things include manipulating the algorithms so that "news" of ones choice get lots of visibility. Then a foreign state can influence the elections

So with my bad math, say a foreign state somehow gets every possible Twitter users vote going their way, at best it's going bamboozle 14% of weak-minded Americans. That's at best, the perfect and unbeatable score. The reality is that most Twitter users are not obsessed with the platform, and most Americans are not on the fence with their votes. This concern is not really supportable.
In addition to that, the manipulators / nation states don't attack only via Twitter, and, everything combined ...
