Unity's position is > Our terms of service provide that Unity may add or change fees at any time. We are providing more than three months advance notice of the Unity Runtime Fee before it goes into effect. Consent is not required for additional fees to take effect, and the only version of our terms is the most current version; you simply cannot choose to comply with a prior version. Further, our terms are governed by California law, notwithstanding the country of the customer. https://forum.unity.com/threads/unity-plan-pricing-and-packaging-updates.1482750/page-45#post-9297488 https://forum.unity.com/threads/unity-plan-pricing-and-packa... They're saying "the terms of service say we can add whatever new fees we want whenever we want." I'm not sure whether the original fee structure that people had agreed to was outlined in the earlier version of the ToS or not. If people agreed to allow Unity to unilaterally change the pricing structure then they may be stuck with it. But if they need to actually change the ToS to make these fees, then I'm skeptical it would stand up in court (IANAL). They made very definitive public statements that people would be able to use the existing agreements with your current engine version, and saying "you simply cannot choose to comply with a prior version" now can't possibly hold water.
