Block Ads in Apps on Android

> Because the app is open source, if it was doing anything shady, it would be found out

This is a little misleading... Just because there is source code on GitHub does not mean the random APK you're downloading from the internet and side-loading is safe.

If you're paranoid (and you probably should be - if I was a bad person and wanted to get malware onto your machines, I'd be making some useful "open source" app and publishing "its source code" on GitHub too), you'd want to build the app yourself! :)

To be honest, most people wouldn't even bother to know if it was open source, they would install it anyway. Actually most people probably don't know what "open source" means.

It would work against the HN crowd though.
