Which is why you add non-copyleft components and make them not really optional. Like for instance their directX-based graphics and cuda support.
Sure, the "core" stuff is protected and you could do without the optional things for now. But how about when for example your favorite machine learning software says "we support linux, but cuda is only supported under WSL", similarly for graphics, rendering etc. .
Sounds a lot what Google is doing with Android (open source) and Play Services (not). They made on purpose harder and harder the use the former without the latter.
