So... abusing free labor?
I stopped working on most of my open source projects because of it. I still open source stuff that I actively use / work on, but don't actively advertise the projects, and ignore any unreasonable request (all MIT, so anyone can fork as they please). Not worth the mental health burden, I get enough of that from my day-job :)
I've yet to get any traction on any of my open-source projects outside of myself, some old coworkers, and a few dozen random people. This morning while looking at someone else's semi-abandoned project I noticed there were 600 unaddressed open issues so I figured I would jump in and try to help some people. After answering the same question for the 4th time (linking them to the official documentation) I started to feel truly grateful that nothing I've released has become popular.
The real problem is that people were sucked into a social network when all they wanted was some easy to manage public code repositories. If that's a problem for you, fight the social network, but this is not an open source problem.
