Sure, but that's exactly the problem. The President having direct control over the visibility of somoene's speech. It's one thing if someone simply isn't popular, and therefore their speech isn't widely seen. It's another for the President to specifically suppress your speech.

It really does constitute a first amendment violation, because it is an active decision to suppress the specific speech of specific individuals.

How does one account muting another suppress their speech? Everyone else still sees the tweet.

Apparently, muting is fine. Blocking prevents comments from showing up in replies. It's a form of moderation.
