you say that like it's a bad or even a surprising thing. for a lot of people that's the entire point of open source development - in their day jobs they do what they are required to do for the company that pays them, and then in their own open source projects they can do what genuinely interests them.
If you just wish to solve your own problems, build things for yourself and keep it private. If, on the other hand, you want to help others and make your software public, then do right by the people who decided to try your software and listen to what they have to say.
How anyone can defend the attitude of the VLC developer in the thread linked above is beyond me.
Why is the artist obligated to do the work you think they should do? Why, if they don't do this work, should they be obligated to not release their work publicly?
FOSS is not an obligation to do everything that every user wants you to do. It's not an obligation to even communicate with those users. In fact, it comes explicitly with no warranty, even for fitness for any purpose.
The developer is a poor communicator, but how anybody can be defending those annoying, entitled, lazy users is beyond me.
