> Freedom of expression only protects you from the government, like freedom of speech, no?

No. In the US, the first amendment to the US Constitution only applies to the government. "Freedom of speech" is a concept with general applicability. People opposed to freedom of speech often intentionally conflate the two but they really are separate things. There may be a genuine argument about what any particular actor should do w/r/t speech - should they adopt a permissive, "freedom of speech" attitude, should they restrict speech, etc. But "freedom of speech only applies to the government" is not a genuine argument, because it's not an argument at all, it's a conclusory statement (and false).
