Earlier quoted context omitted.
> On a privately owned site? Yes, censorship is not exclusive to the government.
Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the Government for a redress of grievances. It's pretty cut and dry that it's exclusive to government
It's not:
> Censorship can be conducted by governments, private institutions, and other controlling bodies.
