China's laws implement the Berne Convention, making copyright automatic.
Open source licenses usually provide conditional exceptions to that automatic and internationally accepted copyright.
So if they don't believe in open source licenses, or whatever, "all rights reserved" is logically the default fallback.
That obviously doesn't marry with what you said. China is famously awful at upholding IP laws they're party to, but I think that's all this is here. It's still against the law there, but nobody cares if it's not hurting China.
It's very easy to say that China —the country— has a problem with intellectual property, but tarring all ethnically-Chinese people with that brush affects hires and promotions in our own countries.
Respecting IP ownership is as much a learned skill as learning to say exactly what you mean when you're accusing a country's governments, police and courts of actively turning a blind eye to IP abuse.
My statement was lazy and could easily read as "Chinese people don't care about IP". You can choose to believe that nothing you say affects anybody else, but enough people parroting the same nonsense has a powerful effect.
How many companies relying on IP laws is "enough" for foreign IP to be taken seriously?
Just one typo in the ph7 readme: powerfull is too german
Even the links at the bottom of the readme are awesome.
