In your example, it feels more like the distributor of the CD now has to pay the copyright holder 1ct everytime you play the CD, from January 1st next year.

But it is license based? Wow, that is quite a risk to take as a gamedev, to tightly-couple your game with a third-party company's tooling, who can change their terms at will, so you can no longer use their tooling.

I understand that you buy a license, but surely you can buy a permanent or fixed license for a lot more money, to take away the risks of having to pull your game from distribution due to licensing restrictions.

It sounds like a dumb move from unity, to create so much uncertainty.
