For what? The damage is done but the engine is still ...fine. They'll have this black eye but they're not dead in the water. If you're an enterprise customer, you'll probably be asking to lock in terms for quite a while, though.
The engine is fine, but existing projects all invested effort into moving off it if they could, and new projects won't touch it with a 50 foot pole.
Large orgs are, indeed, likely locking in terms, but Unity's whole market was basically people building things initially in tiny setups with it, with more convenient access than Unreal.
It's more or less the same mistake flavor that IBM made with killing CentOS - they killed their onramp of the 500000 tiny projects using it because it was trustworthy enough, and that also kills the existence of 50 projects that go onto to be massive successes built on it.
Yet, trust once lost is hard to regain. In the grand scheme of things it’s probably too late.
