I think Unity did a lot more damage than any of the above. D&D is still a powerful brand, and while they angered hardcore fans and creators, the vast majority of roleplayers didn't even notice, and those are their real customers. Tumblr is apparently still around, and OnlyFans is still synonymous with amateur porn. But Unity has only those creators as their customers, and those stake their livelihood on their trust in the company, and with that trust gone, Unity could lose all its customers.
