Maybe, but I think it could have made a small team very wealthy and successful much more than it did a large company.

It was obviously pitched as an ecosystem/platform play, like "the next vmware" or something, but there was never anything close to a real moat there. Running a registry involved a lot of storage and transfer costs plus spam/abuse management, and private registry was always going to be a better fit for being integrated with CI platforms and the like more than a standalone service with its own auth and billing concerns.
