I always thought that they would do this. I suspect that they won't do this to the web store, as there is a fundamental principle in that a web client determines how to render something. That is... the client (browser) can choose to obey or ignore any markup it receives... the end user actually controls the rendering (sizing, fonts, contrast, which elements to display or hide). But apps on an app store have no such principle. In fact the underlying assumption is that they are locked down and that the app author has that authority and not the end user. With that in mind, I wondered how long it would take for AdBlockers on the Play Store that blocked adverts from loading in other apps would be tolerated by Google. Personally I used to use AdAway ( https://code.google.com/p/ad-away/ https://code.google.com/p/ad-away/ || https://github.com/dschuermann/ad-away https://github.com/dschuermann/ad-away ) and you can see the hosts file they use here https://github.com/dschuermann/ad-away/blob/master/AdAway/src/org/adaway/provider/AdAwayDatabase.java https://github.com/dschuermann/ad-away/blob/master/AdAway/sr... , but then I skipped even that step. Now I just root my phone and replace the hosts file with the one found at: http://someonewhocares.org/hosts/zero/ http://someonewhocares.org/hosts/zero/ I wouldn't say that AdBlockers are all bad, one of AdAway's features is that you can load hosts lists to unblock domains that were removed from DNS in countries like China: https://smarthosts.googlecode.com/svn/trunk/mobile_devices/hosts https://smarthosts.googlecode.com/svn/trunk/mobile_devices/h... Edit: Although now I'm curious... have Google gone so far as to prevent people from loading something like AdAway from an untrusted .apk like the one AdAway host at https://f-droid.org/FDroid.apk https://f-droid.org/FDroid.apk ?
