They were already paying for it. The subscription model should be enough. It scales well enough for small devs to make decent amounts of money, and for Unity to get paid. You act as though indie studios are using this tool for free when that is hardly the case. Past a certain revenue amount, they are required to upgrade to a paid license which is totally fair. Game not taking off? No worries. It is just wasted effort. Game take off and you make lots of money? GREAT! You get to upgrade to a paid model of a tool you already use. It was a WAY more fair model. If they are that hard up for money, they should have just announced a subscription price increase. Not retroactively price gouging for games that have already been released.
