No, it doesn't need to, that's part of my lament about using a permissive MIT license rather than a GPL one.

If they use Godot completely out-of-the-box with no customization, then nothing. But the parent commented noted that they use it for their car visualization. If they made an internal fork to add in some performance tweaks, that would be the kind of thing that would benefit the community as a whole if it's upstreamed.
And maybe Godot decides those changes actually aren't useful to anyone else and disregards them. But they might be, and that's the key.
It was rhetorical. Anyhow I'm happy it's MIT it makes selling proprietary apps more straightforward. And the Godot foundation has plenty of sponsors to keep the main devs happy anyway.
I also heard the main "tweak" in Tesla's code is they basically just use the renderer on its own versus all the game engine features.
