Sure. I can't talk about specifics but I've worked several places where GPL code was forbidden, particularly in products we built that were installed on premise, and LGPL regarded with suspicion. (IANAL) LGPL isn't generally a problem (from my reading of it), but it gets grey the moment you include a library (even unmodified) that is released under GPL. And this is where everyone starts getting nervous, regardless of whether it's OK to do that without handing over your source code or not. That confusion, if it is an invalid concern, suggests that at the very least the GPL does not do a good job of explaining itself.
