"Freedom of speech is an ideal that applies to all people and all spaces, public and private"

Since we can't agree on a definition of "freedom of speech" this doesn't mean much.

In practice it seems to mean something is a "freedom of speech issue" when a speaker wants someone to not face social consequences for some action (For example an Elon Musk fan saying he shouldn't be charged with investor fraud because "freedom of speech"), and when a speaker wants someone to face social consequences they stay conveniently silent. (Say, an Elon Musk fan not complaining when he fires an employee for something they said).
