It's not that hard to understand, I think. Through work, I 'own' the domains for several of my customers simply because they're too busy and not tech-savvy enough to register things themselves. So I register them, do the configuration etc. but I'm listed as the domain holder, not them.
I wouldn't do it of course, but it'd be easy enough for me to do whatever I wanted with the domains should I have a falling out with those clients. I could post whatever I wanted, while they had to register a new, different domain, then try and re-establish themselves with the new domain while I posted claims that they were fakers or whatever.
Yeah I know there's legal means that could be used to get the domain names transfered -- here -- but I've no idea if they can do that sort of thing in China.
Anyhow, at this point I'm wondering whether it even matters. I mean, I have two dingoos from two different sources. They are different inside and out. One has a paw print and the dingoo digital name on the back, the other doesn't. One has a blue circuit board and a "chinachip 3200" cpu, the other has a green circuit board and the cpu says "ingenics jz4740". But functionally they are identical. And quality-wise, they are the same. Neither seems shoddy or poorly-made. They both run the same firmware, they both run Dingux, they both have the same specifications (ram, flash, etc).
So what does it matter who made them, or if they were made by different companies?
