Trust is hard to build and easy to break and even harder to rebuild.
To truly rebuild trust, they’d need to commit to never doing this again. That would mean 1. a change to the legal TOS that a developer who licenses for a project at a certain pricing level may remain at that price level for that project / that generation of Unity for as long as they wish, 2. a public commitment to never require per-install pricing, and ideally 3. the resignation of whoever came up with this brain dead idea.
To truly restore trust, it should be ‘we’re sorry, our mistake, it won’t happen again, our new TOS will guarantee the right to remain at a current license price structure for a given generation of the engine, we hereby promise to never ever require per-install pricing, and the person responsible for this change is no longer with the company’.
This is bullshit. There is no confusion. Their new policy was very clear and easy to understand. If the word confusion applied at all, it would be to how/why Unity is doing such a brain dead move that alienates their entire user base. This is a weasel word announcement that doesn’t say what it should, namely ‘we fucked up and we’re sorry’.
