It's also catastrophic for services like Game Pass where the developer gets a flat fee regardless of how many people install the game. You can take a flat fee that seems reasonable based on an expectation of 100k installs, but then your game turns out to be a smash hit and it gets a million installs. Now you're on the hook for a massive amount of money to Unity but the money you got is barely enough to cover it, if it covers it at all.
