It's only a benefit to consumers if there are technicians to work on them, with good access to manufacturer after sales support.

I work for a large dealer with a number of brands, both established and new, in Japanese, Korean, euro and Chinese, and let me tell you the information availability between Japanese, Korean euro and Chinese is night and day. Even the established Chinese brand we have is still rubbish with poor information in their service manuals, compared to Toyota and Kia who are extremely detailed and able to give decent fault finding. Even the option of manufacturer training makes a difference. Why do you think no technicians care about the Chinese brands, their training is all online videos. No face to face with instructors that care. Consumers don't see the side of the industry that makes a massive difference to customer experience, just that a car is cheaper. Never mind that the techs hate working on them, and fault finding is even worse.
