I don't find it hard to believe at all. The simple fact is ideas are cheap and everyone is full of them. Execution matters. The idea does not.
An NDA is appropriate for something that is a bit closer to fully baked than just an idea. If you've got a proprietary algorithm or business database that you don't want to leak, then an NDA is appropriate. If you're demanding an NDA just to talk about an idea that you haven't even started working on yet then you're just wasting time and oxygen.
