Absolutely! Every minute spent on fine-tuning an ad SDK is a minute not spent on making the app better for paying customers. Most of these SDKs are not just drag and drop, either; developers have to spend a lot of time configuring the attribution schemes and to update them periodically.

There's a huge international market of potential app users that tolerate ads but would never pay to purchase an app. Even in affluent areas, many people balk at a $0.99 app but are totally fine with ads. This, of course, is the entire business model of Facebook, Instagram, etc.

The billion dollar question is: how do you monetize non-paying users, at scale, without ads?
