This ban runs against both of those.
It is absolutely a strawman:
> A straw man fallacy (sometimes written as strawman) is the informal fallacy of refuting an argument different from the one actually under discussion, while not recognizing or acknowledging the distinction.
Grandparent: Please, US doesn't need to prove anything w.r.t freedom vs. China.
Parent: So you're saying the USA is better and thus it never needs to be compared in any aspect related to 'freedom'?
Me: GP didn't say the USA never needs to be compared in any aspect related to freedom, they said _relative to China_ the US doesn't need to prove anything.
It's objectively a strawman.
That's separate from the issue of whether or not this infringes on the freedom of speech, but 1) freedom of speech in the US is not nor ever has been absolute with no limits and 2) this move absolutely deserves scrutiny.
