If you really want to do something. Please hire them! 
I was joking…
This is apparently a political issue of China, and Python Community is better to be non-political.
We should show understanding for them, but we can’t change the fact.
If we are going to apply the 996 license for Python, then China’s companies could simply create a fork from the last non-996-licensed version and maintain that by themselves. Then, the offical Python disappears in China.
Another fact is that, even if those companies don’t follow the license, we actually could do nothing 
China is like an separate world, and they don’t care the rules in open source communities.
