Reading it, seems like the downvotes are deserved.

Downvoting prevents other people from seeing his comments. You need to upvote to make sure everybody sees "his own words", as he put it. That's for the common good.

No doubt. He and many others would conflate it with people agreeing with him.

It's not just him. Nobody uses upvotes for the purpose of "letting others see it". We are supposed to do that but we don't.

Almost always when someone shows up I upvote to thank and encourage them, but that's really hard to do in this case because he's doing exactly the behavior outlined in the article.

It truely is a car crash.

It seems like he can't stop and will end up in court at some point.

LOL He show his github profile, private, and it has a link to the competitor. To me this reinforces the linked article.

Nice competitor you have there, would be a shame if someone did the same to it.
