I thought the Adblock Plus approach to this was interesting, where unobtrusive (or "acceptable") ads were whitelisted by default, and they were quite clear about the criteria for this as well.[0]

But the tech community lost their collective shit and threw around loaded terms like "extortion", "mafia" and "protection scheme" (I'm not exaggerating, search for those terms on this domain), which made any nuance impossible.
