But you said "Yes" two lines above.
> They are common carriers.
These common carriers are private companies, not public companies. They aren't owned by the government. They are owned by private shareholders. AT&T, Verizon, T-Mobile, etc are private companies or non government entities.
> Twitter and the vast majority of other companies are not.
I never claimed twitter and the vast majority of companies are. I only responded to the assertion that all "non government entities" can censor. I was providing proof that some non government entities cannot censor.
