We are going to disagree on the TOS changes; Improbable were always in breech, and yes their users were too (which imo is Improbable's mess to sort out), even before the clarification updates. The changes tried to spell out, clearer, what was already part of the problem, yeah they aren't clear and miss the intent but it doesn't change the facts that Improbable were in breech long before those changes occurred and should have informed their users as such - unless you are proposing that Unity should have had access to Improbable's customer list and gone to them directly?
Also, the concept that they "change the rules to put people in breech" would have only applied if those people had updated Unity AFTER the changes occurred - as spelled out in the reply from the blog quoted above. The fact that Improbable remain in breech with that logic applied means this goes beyond that 4.2 update/tweak/whatever you want to call it, as they can't be in breech if they haven't updated.
Should Unity have put out a blog post saying they cut off Improbable when it happened? Maybe... of course all that would have happened then is it would have looked like Unity were trying to strong arm Improbable via the court of public opinion to hand over money to keep their business going. (and my understanding is that replies to an initial Improbable statement about this had been prepared, just no one expected them to come out and just lie about basically everything.)
I personally hope more details do get out in the wild so that both Improbable AND Epic get a pasting over this... while Unity and Epic have been rivals for some time there has always been a kind of code, or respect, between the two - hell Tim was even complementary about the ECS stuff when it appeared back end of last year (and he'd been heading back up in my estimation, now however...) - this seems to have changed the rules of that game a bit imo; heck maybe it was the ECS stuff that rattled Epic and they've seen this as an opportunity to strike back without having to take a technical lead? That we'll never know.
