Agreed. The more EV manufacturers the better. Many will fail, some will succeed.
Every new product draws on work done by others. Tesla drew on the work done by lithium ion cell designers, AC induction motor designers, touchscreen display designers, etc. etc. etc. and then combined it all into a new package that went beyond previous attempts, creating a very compelling product. This new Chinese company may or may not be taking things a step beyond Tesla, we will have to wait and see.
Yeah, it is funny... I had rare opportunity to use Xerox Star computer, and when the rip-off Apple Lisa came out, I was one of the first to see that. That was also a more or less identical "rip off", yet there are a couple of subsequent generations that see Apple as the big innovator. And they were/are. Not saying it will be these guys, but if someone builds upon and outdoes Tesla, that's overall a great thing. Guys like Elon will never run out of "change the world" challenges (hyper loop?)
