What are the other requests that the author receives? This list seems to still include every option of interaction over an issue as being acceptable, so I’m not sure what behaviour they’re tying to discourage?
Some time over the last ten years or so, much of the open source community acquired the belief that they deserve to be treated as a customers despite the fact they don't pay for squat.
* "Can we get an ETA on this? Some of us need to get real work done"
* "How you can justify leaving out such a basic feature?"
* "This project is unusable without this feature"
* "Why waste people's time by releasing software with bugs like this"
* "This kind of mistake is totally unprofessional"
* "The developers must not have the skill to fix this"
These sorts of interactions can be more exhausting than outright abuse, because they're designed to bait/provoke the developer rather than just insult them. And to be clear, this isn't particular to this developer. There was a whole study done on this that made the rounds awhile back[1].[1]: https://www.cs.cmu.edu/afs/cs.cmu.edu/Web/People/ckaestne/pd...
