Holy straw man! And there’s certainly no self-interest involved with me using their engine without giving them a cut under 1 mill right?
You can make this argument about literally anything.
Godot must have no self-interest in releasing their engine for free and making $30k a month to develop their project.
Who cares what the motivation is if it gives real benefits to devs. If anything it tells me they’ve picked a business model that’s mutually beneficial unlike Unity
