> If the app is free but offered by a commercial entity, they pay nothing in commission or payment fees (13% X $0 ) but they reach 1 million installs, then they do have to pay €500k. If the business has no revenue - that’s a weird business model.

I think that "growth first, revenue later" is actually a fairly popular business model, and I can imagine a lot of my own app ideas reaching 1M downloads with <$500k revenue (in an ideal world, but still)
