If you don't understand the authors frustration, read Daniel Stenberg blog about what kind of requests he gets about curl. It's insane and ridiculous, not everybody is capable of/wanting to deal with all kinds of shit and hostile users like Daniel.
In this case it clearly hasn't happened to this author (yet) AND the nixos devs have put forward a selection of reasonable proposals to prevent it happening to him. All of which he has rejected without and real justification.
If you read the full thread it becomes clear that his citing fear of support burden is not made in good faith. His acts of blocking redistribution of his package in any Linux distro (here & Fedora at least) is clearly a bigger burden for him to take on than he would take on if he allowed the redistributions.
