Free apps eat up your phone battery just sending ads

"This app is awesome! It makes my phone free of ads. I get spoiled with it. I now ever have to buy an app that only offers no more ads because of this app."

"Pretty much turns free apps into their premium ad free counterparts! ..."

Please keep in mind that ...

(1) Developers in many countries are not yet able to sell Android apps on Google Play store. Ad revenue may be their only source of revenue.

(2) Android users already have a reputation (well-deserved or not) for preferring free apps, or for pirating paid ones (more so than on other platforms). This is another reason some apps on Android are ad-supported, even when the developer could choose sell them. (A well-known example is Angry Birds). If blocking ads becomes a common practice, this will make the Android platform less attractive for developers who seek to make a living from their apps.
