If no one is willing or able to defend constitutional rights, they don’t really exist any more. I hope there are legal cases being prepared at least, to challenge all this new censorship.

When the government is acting as an employer, they mostly aren’t constrained by the First Amendment in the way that they are when acting as the government.

Restrictions based on special capacity of government

As employer

The government is not permitted to fire an employee based on the employee’s speech if three criteria are met: the speech addresses a matter of public concern; the speech is not made pursuant to the employee’s job duties, but rather the speech is made in the employee’s capacity as a citizen; and the damage inflicted on the government by the speech does not outweigh the value of the speech to the employee and the public. Specifically, speech is “treated as a matter of public concern” by reference to the “content, form, and context of a given statement”. The exception with regards to balancing the harm of a statement and the value of the statement (the Pickering test) is done by considering the degree to which the speech either interferes with close working relationships, disrupts the office, or even has the potential to do either.

Most on-the-job speech is probably going to fail the “pursuant to the employee’s job duties” test.
