My "despicable" side business is (was) making Android apps with Admob ads. I needed to update my app to allow EU users to opt out of targeted ads. Why Admob doesn't just add this functionality to their widget they place in my app is beyond me. In order to update my apps, I need to target a newer version of Android. It's not that it's very outdated, they were targeting Android 5.0, and get updated every 6 months or so. But a change in the Android API has made this very difficult for me. Being a side business, I had to make the choice - let go of the $600/mo I was making from ad revenue, or continue with the constant barrage of code updates required from Google for my apps to work. I decided to let it go. My app would still be on Google Play, even though I couldn't update it, if it weren't for GDPR. They pulled it due to non-GDPR compliance. So, yeah, GDPR has costed me $600/mo. I'm sure there are a lot of others with complex stories about how these regulations affect them. BTW I support GDPR and privacy as a whole, and wish my native USA would take privacy more seriously. It is the details of the implementation that are lacking. I also suspect that Google uses policies (such as putting the burden of Admob GDPR compliance on the publishers) to try to push out small developers.
