Well the internet is a commons and you know what happens to those.<p>Perhaps do some A/B testing, and see what happens statistically when you block some people from using the site with an adblocker, beg some of them to disable the adblocker with a popup, etc. This will tell you information about how desperate the users of your site are to get to your app, and will contextualize how much of that potential revenue you think you're losing is actually real.
