I am not talking about judging his 'worth as a person'; rather his 'worth as a developer.' Maybe in his private life he's a wonderful person, who knows? Who cares? It is his professional activities that concern people.
You are of course welcome to have an opinion, and to choose whatever product you want based on that opinion. But if the extent of your opinion is "this person is a jerk and their work is terrible and not to my taste" that is unlikely to convince that person to change course, especially if they don't know you and if the decision is already made.
Furthermore, the "this person is a jerk" part is clearly not part of some dispassionate evaluation of his professional accomplishments and is just a verbal attack couched in the language of professional criticism.
I suspect that, in many instances, people who do that are not trying to convince anybody of anything. If they expected to be greeted everywhere with agreement then they would not go around saying things which they know perfectly well are not likely to result in a vigorous and healthy debate if they were said to strangers in the street :)
We've banned this account. Please don't create accounts to break HN's guidelines with, no matter how strongly you feel about something or someone. We're trying for something else here because it's the only way to keep the site interesting.
From some of your other comments I gather that you've been around this material for a long time and you know a lot about it. Why not share some of what you know, so others can learn? and make your substantive points thoughtfully? Then you'll be making this place more interesting, and your points will have some persuasive power. Just venting only adds energy and credibility to the views you disagree with.
I get that there's a low probability this argument will work with you but I think it's worth trying to persuade people that it's in their own interest to follow the rules, which are designed to try to keep a community that's interesting for everybody:
