Don't you just hate the viral nature of infectious *proprietary* code? To co-opt some propaganda used against GPL in the past: Using a proprietary library in your application mandates that significant swaths of your application be released proprietary as well. That's not a problem if you wanted to release proprietary software to start with, but it's a problem for anyone else on either side of the spectrum. For this reason, developers have to be quite careful about how they use proprietary software to make sure that it doesn't impose unwanted licensing restrictions.
