I'm not a free-speech absolutist but I've met some. Generally, I've only ever encountered discussion of free speech to be in regards to one's rights to voice their beliefs, opinions, and criticisms. That usually will apply to defamation (but with the right of the defamed party to sue, especially if the claims are false). There's probably some division about where threats cross from speech into violence, especially as threats can themselves be used to restrict freedom of speech. Likewise for yelling "fire" in a crowded theatre.
I don't think even free-speech absolutists apply it to a general right to share any arbitrary information, such as copyrighted films, classified war plans, trade secrets, doctor-patient or lawyer-client privileged information, or intimate recordings of people taken without consent (or without ability to consent).
