Exactly this. Bug reports were very welcome! While I stated that the API would not expand any longer in some projects, I also considered coherent feature requests a positive, and normally suggested and guided those as a plugin that lives within their codebase.

The problem was when people came like "I am using this library, can you debug my code?" and pasted a 500-liner, or like "this doesn't work on my XYZ system, fix it", or when they were just rude or demanding.

I've met some wonderful people BTW, and would also not trade that for anything.
