It is a free speech issue. It is not a First Amendment (or equivalent in non-US jurisdictions) issue. Legal provisions that protect speech from government interference provide a minimum level of free expression; in a health society private citizens and organizations will generally go above and beyond that minimum.
"Freedom of speech and expression, therefore, may not be recognized as being absolute, and common limitations or boundaries to freedom of speech relate to libel, slander, obscenity, pornography, sedition, incitement, fighting words, hate speech, classified information, copyright violation, trade secrets, food labeling, non-disclosure agreements, the right to privacy, dignity, the right to be forgotten, public security, and perjury. Justifications for such include the harm principle, proposed by John Stuart Mill in On Liberty, which suggests that 'the only purpose for which power can be rightfully exercised over any member of a civilized community, against his will, is to prevent harm to others'." https://en.wikipedia.org/wiki/Freedom_of_speech
Additionally, private companies can always throw you off their platform for any reason. No shirt, no shoes, no service.
