I mean, in my opinion, it isn't a big deal with regards to whether or not asking is a 1A violation.
If you are talking about the a more general ideal of "open and free speech" - which private companies are never legally required to uphold, but may choose to espouse anyway - then it's clearer to say that instead of conflating it with the First Amendment, which will just distract others from the points you're trying to make.
I guess people's argument then would be that the govt (or whatever) indirectly limited Twitter user's speech.
