Earlier quoted context omitted.
I really appreciate your approach to this argument. You really cut through any strawman fallacies by pointing out that there's a debate along a spectrum about what protecting free speech entails, but that the President needs to have limitations in his power over private companies. I think this final point is not debatable in a legal context; he does not legally have that power.
Darn right he does not have the power. Either the president does not know the constitutional limits on his power, or he knows them but still thinks it's a good idea to claim power that he does not have. I'm not sure which is worse.
Or he knows what he is allowed to do and is just saying stupid crap like he usually does. Trump doesn't have a filter and just says/tweets whatever pops into his head. This could be another example of that.
