>There should me more push for really open engines, as in FOSS. Unreal might be more open than Unity in some ways, but it's still not really open.
This just isn't possible with game engines. They are the single most advanced pieces of desktop software in existence. Sure, there are things like Godot that are perfectly suitable for a simple indie game. But making a AAA game engine requires the expertise of literally hundreds of top level senior engineers with advanced physics and mathematical knowledge. There's probably less than a few thousand people on earth with the level of skill and expertise to build something at the scale of UE4. Furthermore, open source is really the exception to the rule in game dev. Practically everything is done closed source with some kind of licensing fees involved. It's quite a different culture from web dev.
