I went to a secure coding conference a few years back and saw a presentation by someone who had written an "insecure implementation" playground of a popular framework.
I asked, "what do you do to give tips to the users of your project to come up with a secure implementation?" and got in return "We aren't here to teach people to code."
Well yeah, that's exactly what that particular conference was there for. More so I took it as "I am not confident enough to try a secure implementation of these problems".
