Also, anyone and everyone who has had a dissenting post deleted/removed from Twitter should join together and file a Section 1983 suit against Elon for depriving them of their civil rights. Because the facts make it a pretty damned solid (and important) case.
1. Elon is a powerful, senior employee and officer of the US Government. Trump has admitted so, publicly. Further, Elon's public statements and tweets on the matter make it clear that he is.
2. That powerful, senior officer of the US Government controls a major site for the dissemination and public discussion of topics that include the operation of the US Government, specifically including the functions of that particular officer of the US Government.
3. That powerful, senior officer of the US Government actually USES that site for making statements directly connected to and relevant to his role and actions as a US Government official.
4. That powerful, senior officer of the US Government suppresses/drowns out dissenting speech by a) actively deleting/hiding dissenting posts and comments, b) creating/directing the creation of an algorithm that performs the same function.
5. Government suppression of speech, particularly on matters of public import and interest, is a plain violation of the First Amendment rights of the speakers.
TLDR: Because Musk is an officer of the government and does not just use but CONTROLS Twitter in connection with and in furtherance of the performance of his duties as a government official, Twitter is -- for First Amendment purposes -- an arm of the US Government. Thus, it cannot suppress or favor any speech based on its content. Doing so violates the First Amendment, and Elon (in his capacity as the owner and controller of Twitter) should be enjoined from doing so.
It is a good lawsuit. It is a VERY good lawsuit. It should be brought posthaste, seeking emergency injunctive relief, because the harm is real, ongoing, and there is no adequate remedy at law if it is allowed to continue.
