The Unity thing is so bad on every level. At best it rips off game makers; it can be abused to screw game makers even worse; Unity implicitly admit that they didn't plan for this; their mitigation completely relies on their competence and good will; there is no reason to assume good will because a business will always want to charge you more not less, particularly where the circumstance is unclear, which is exactly the circumstance if you're arguing some downloads weren't "legitimate"; They are always going to believe a larger number were "legitimate" than you believe, because it benefits them, and only they have the power to verify it; and finally they were immediately awarded a better credit rating for adopting this scummy plan.

I hope their shitty company dies but they will probably make enough money doing this from giant games.
