When I see a GPL license I don't see freedom. I only see forced openness, which makes me immediately avoid that library, since I can't statically link to it.
One of the arguments in favor of GPL and other "forced openness" licenses is that users should have the right to understand what their own device is doing. You paid for your computer. You own it. You should dictate how it operates. You should at least have the option of understanding what is being done with your machine and modifying it to fit your needs. Closed source software may provide utility, but it doesn't really further collective knowledge since you're explicitly refusing to publicly release the code, and it provides obscurity for developers to hide undesirable functionality like data collection or more directly malicious activity.
I'm not personally sure how I feel about that argument myself, but I can at least readily acknowledge it as a valid one whether I agree with the decision to force openness or not.
