Was reminiscing about the early iOS App Store days when many apps were free and often hobby projects. Some hooked up google ads to make a nice easy profit if they stumbled on a particularly good early app idea. I don't really find apps like that anymore, or at least they don't really get shared the same way. Maybe this is a return to that in a sense.

I also don't think any particular idea is off limits for making a profit, if you do something and you do it well, you can charge a fee. But if the free hobby version is better then you best find a way to justify the price.
