Someone should make sourceavailable.com - A service that automatically pulls my private repos from GitHub and makes it available as open source to other programmers. A read only version of GitHub, without the isssue/PR overhead.
Some people did close the issues and store them in a directory as plaintext on the repo. Want to report a bug ? make a PR. the extra little friction was added so that you need to spend a little time (and having spent that little time you might as well research a bit your bug or read the doc). Bonus point, your project is now completely portable.
