I'm not pointing it out to switch it out. Rather, I've heard from many GPL proponents that linking/importing GPL in BSD code is fine, and saying the opposite is simply FUD. So I'm wondering whether SPORCO is unwittingly illegal or simply bearing this out. Know of any cases where this has been specifically tested?

You can combine GPL and BSD code, and it's certainly not illegal; it's just that you may have to treat the combined work as being under the GPL.

And advertise it as such; whereas scikit-image explicitly labels itself as BSD. In a sense, not too dissimilar from packages released under BSD, but then implement patented algorithms. You have to make your users aware of what they're getting themselves into. Stéfan
