Bumping this up although I know Epic will never give a ■■■■.
At this point I believe it is a “in-company attitude” type deal that they will not deal with it because of a non-discussable ideological reason rather than some physical reality.
But I agree with the idea of “Unreal Engine is not free. We pay for it with our income” thing. If you ask for money for your service it is not free.
Finally yeah. I was (still somewhat am) an Cry-tech fanboy who later switched to Lumberyard (which is still in Beta) and finally Unreal. Both of these engines are on github so the thing is really not “hard to understand/formulate” . It is just Epic does not care.
Here is a random related pic to finish. Good days mates.
