Aren't there pr firms you can hire to help with this, and focus group and whatnot so you don't have to enrage the internet and then issue "clarifications". I'm always amazed when big companies are so bush league. Hire a consultant to help if you're not sure, they've probably lost millions in goodwill over this.
Edit: to clarify, I'm not really talking about the policy change, more the way they announced it, received all kinds of criticism, then "clarified". There may for example be a business reason why they are ok with pissing off some customers, but why not get the messaging right the first time?
Unity's model is still WAY kinder than Unreal's for virtually all pay-upfront games, but there are degenerate failure cases, particularly around f2p mobile games, where you're on the hook for catastrophic amounts of money; Unity's seeming unkindness around that (e.g. not implementing a 5% revenue cap, like Unreal) is also concerning, and I'm not really sure why they're not handling this with more care.
