Google can make it more difficult but it’s like anti-cheat, a losing arms race. In the end users control if adverts play even if Google controls the computer as strictly as North Korea OS.

Words do not have innate definitions and “piracy” can mean whatever you want (when not in a court of law). If people understand what you mean then no direct issue. Due to the association with stealing and murder on boats I won’t call copyright infringement “piracy” (thanks music industry propaganda) or blocking adverts. If you insist on calling me a pirate I will respond with pirate talk, ye landlubber.
