No problem, and thanks for the frank follow-up.<p>--<p>Regarding the ISP part, I fully agree it would be tough to implement; I was throwing this idea because I had never seen it being expressed and wanted to see if commenters could point to related &quot;prior art&quot; &#x2F; similar experiments in some parts of the world.<p>Mainly, my own starting point for the idea is France&#x27;s (and maybe other countries?) interrupted path to a &quot;Global License&quot; for music [1]. The idea, expressed as a law proposal in 2005 at a time of majors freaking out about P2P, was to (fr.wikipedia translation mine) <i>&quot;Authorize non-commercial access and sharing of cultural content, in exchange for a proportional artists remuneration.&quot;</i><p>It was interrupted in 2009 in favor of a repressive fine system (HADOPI, [2]). But if such a very much pie-in-the-sky idea can make its way to a law proposal (with assorted technical analysis) somewhere in the world, maybe something similar is worth discussing for ads.<p>[1] (french) <a href="https:&#x2F;&#x2F;fr.wikipedia.org&#x2F;wiki&#x2F;Licence_globale" rel="nofollow">https:&#x2F;&#x2F;fr.wikipedia.org&#x2F;wiki&#x2F;Licence_globale</a><p>[2] (english) <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;HADOPI_law" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;HADOPI_law</a>
