GPL can contaminate you when shared as a dynamic library under certain circumstances. But that doesn't matter, since there are few mainstream libraries in these communities licensed as GPL. Nearly all of it is MIT or Apache.

There is no such thing as contamination.

GPL code doesn't change the license of your code. It only prevents you from using GPL code from your code.

This is a distinction without a difference. If I must use it, I’d have to GPL my code.
