Because it's so cheap, nobody's going to make the effort to translate the documentation into English and put it on the Internet. But on the other hand if you go there and ask in Chinese you can get quite a lot of information.
On the other hand, just translating the documentation of this led lightbulb interface would have taken very little time, and would have probably created a nice app that would appeal to western buyers and increase sales.
Maybe there's an opportunity for some site to make this process happen ?
"There are almost no Chinese makers in Shenzhen doing it purely as a hobby. I’m pretty active in the community and I have not met them.
Our makerspaces — the few real ones we have — are primarily for educational purposes. We have a couple of places with laser cutters or a small 3D printer for the kids to learn on, but there’s no place you can go swipe a card and use real machine tools in the middle of the night like lots of other major cities have.
...
As far as most Chinese people’s thinking, hobbies are for old people. If you have seen newspaper articles about actual Chinese makers — who have made homemade robots, dialysis machines, submarines, prosthetic arms — they are nearly all older or retirees. Young people in China just don’t have the time or freedom usually.
...
On the other hand, if you are working on a hardware startup or just want to get stuff made, then sure, I think Shenzhen is pretty unbeatable[for making]."

There's also a lot of stuff at seeedstudio.com or electrodragon.com that is open source too.
Also, this episode describes where China/Shenzen is at right now https://www.youtube.com/watch?v=e4wbFdePb-k
I've bought stuff from seeed studio before. Nice stuff, nice people. Obviously your mileage may vary WRT individual pieces of hardware.
For example connected stuff(either to app or site). Also there's a case to be made for letting people change the embedded software inside their bluetooth headphones, noise cancelling earphones, routers,mp3 players[1], android tv boxes, and any other products with complex software.
