If you do not reach a certain revenues in the last 12 month there is no fee, free app are not touched by this in my understanding.One of my companies has an app written in Unity that has 100k+ users. It's a free app that only exists to supplement our hardware sales. The fees are not enough to bankrupt us given our low user count relative to a mobile game or something like that, but it's still an unplanned hit off EBITDA. This honestly might be the push I need to re-write everything in a different language, I am not convinced Unity was the right one to begin with for the type of app we have.
deciding there is a "credible" threat against them tends to be very suspect
Yes I am sure they received a lot of them but credible could be being very generous with the term.
