Just because something is open source, does not mean you have to engage with the "community". Slapping GPL on some code on a git repo somewhere, with a big sign saying if you don't like it you have the right to fork, so please fork off, is also open source, and a totally ok thing to do if you don't want to develop a community [Open source maintainers don't owe the world anything beyond what they freely want to give it]
