Can't a simple solution be: websites detect if their ads are being blocked (by iOS9 or whatever) and blur their content until the user disables the adblock?
It's the same with content. If I go to read your article and you block it because I'm blocking ads, I'm not going to tell anyone about it and I'm not going to share the link. You then don't get the ad revenue from that sharing, so it's a net loss for you.
(And of course, if I go to read it, and it says I need a special app, I'm also not going to read it or share the link.)
