I use Godot and now I'm wondering if this can't happen at Godot as well. Perhaps it's time to switch to Unity. You pay but at least they have sort of stood the test of time.

No, it most definitely is not time to do that. This can't happen to Godot, since FOSS licenses are irrevocable. It can happen to Unity. You'd be moving from a zero chance to a small but nonzero chance if you did that.
