If I understand the EULA correctly you cannot use Unity with different subscription plans in the same project. What does this mean when working together with different independent developers? Let's assume that I own a plus or pro subscription that I also use for my own projects. Does this prevent me from contributing to an open source game written in unity? Most collabortators of such a project probably just use the personal edition. What about joining a team for a game jam, if the other team members all use personal editions? I thought I can just solve this problem, by installing multiple versions of unity with different subscription levels for different projects. However this seems not to be allowed. To me it seems, that upgrading my unity license would prevent me from working with lots of people. Am I missing something?
