I once accepted to do a customized version of an open source application I'm working on, and I realized half way through that they were using it for recreational hunting which I'm opposed to. To be clear I don't mind people using my software for things I don't necessarily approve of, this is the nature of open source, but this felt like directly and personally helping them and that left a very bad taste in my mouth.
