Wow. Talk about a bad response though. No matter how abused you may feel as the sole maintainer you should still not throw a tantrum. Censoring an issue title, body, and comments is a gross overreaction. If you want to throw in the towel then just throw in the towel.

From the maintainer point of view, it seemed to have been the straw that broke the camel back, but I don't know the whole background.
Still seems like a sad story
