In my completely uneducated opinion based on heresy China seems to care a great deal less about intellectual property, patents and licencing right of companies that aren't Chinese.
Given its regular practice of trying to get companies to manufacture goods in Chine to steal their process' and technology.
This is also the exact reason SpaceX don't file patents and do not use anything from Microsoft.
You see, Russia isn't that caring about copyrights, too. There were relatively recent (this happened after Windows XP release) industry lobbying that led to massive rewrite of copyright laws, but illegal copying is still nearly ubiquitous.
If this is really about security and not to pull off exactly that above.
