It doesn't work the same here as with B2C products. Excluding hobby developers who wouldn't been hit either way. most people paying for Unity are trying to make a living and a company eradically throwing the pricing model around is not a good look when there are altrnatives around.
People can and will go to alternatives for new projects. Unreal, if you want a marketplace and impressive 3D and Godot if you want FOSS. Not to mention the otber game engines.
It's about money here, in some cades not little amount of money.
