I found a study [0] from Q2 2015 -- before iOS 9 -- that reports ad blockers on 16% of <i>devices</i> in the US, and on 36.7% of devices, the highest value, in Greece.<p>I have Javascript turned off by default and sometimes enable it if pages don&#x27;t work otherwise. Sometimes I just leave the page. I don&#x27;t see it as ad blocking, but as a means of reducing attack surface, tracking, and improving page load times.<p>[0] <a href="http:&#x2F;&#x2F;downloads.pagefair.com&#x2F;reports&#x2F;2015_report-the_cost_of_ad_blocking.pdf" rel="nofollow">http:&#x2F;&#x2F;downloads.pagefair.com&#x2F;reports&#x2F;2015_report-the_cost_o...</a>
