I wonder how many bugs go unreported because the team or individual responsible for the code-base is too difficult to deal with it's not worth the time. Those that aren't indifferent to feedback are often hostile to it and will get pretty aggressive when you point out flaws. Additionally, many of these code-bases are so esoteric and needlessly complicated, many with quirky coding styles unique to the project or with layers of meta-programming that makes it hard to understand what's actually going on unless you've actually worked with that project for a while. When I see M4 in a project I just sigh and move on.
