Incorrect, hello99. Rav Elyashev holds there can be no intellectual property protection on a voice (i.e. music.) You are also mistaken about most of the others and their position. Provide citations for your claims for all those sources that anything other than hasagas gvul is at stake. At most, if at all.
Additionally, what I stated earlier above is the position of various poskim that can be relied upon even if some other pokim disagree and hold there is intellectual property protection al pi din.
As an aside, Torah publications also cannot be protected from dissemination as IP.
