I recently found out one my favourite FOSS projects was abandoned due to bullying. It was a small project and very fresh so it obviously came with some bugs and issues which is a given. The maintainer gave up only few months after because of all the negativity.
The latest one was LSPatch. Did so much for me. Last message from the maintainer was something along the lines of ‘Seems like people are not happy with the project so I’m dropping it’.
