I assume you quesitoning why the recordings should be prohibited? The act itself is so disgusting and enraging. But I assume you mean the act of trying to regulate it? Because it was obtained at the expense of the individual and without their consent. When you release something into the public domain intentionally that is a different story, with like, say, ****. Or music, or software. Granted "licenses" are created to guide their distribution into the intended channels. But at this point privacy is no longer an issue.
So if someone hacked my computer and stole a song I hypothetically recorded and did not intend to distribute I would want it back. But when I release it for the world, its fair game.
