Earlier quoted context omitted.
Sounds like Vlad did a pretty sane, human thing reaching out and offering to discuss. The authors replies seem pretty rude (or at least somewhat aggressive / dismissive). Kagi is Vlads baby and I could imagine he would care and try to explain when he thinks someone has the wrong idea. However to the author - it’s just another service he doesn’t use anymore.
You can make that argument for initial approach, but it falls flat on its face after the author told Vlad that they didn't want to communicate with them and Vlad responded with a lecture. Vlad comes off as fairly unhinged here.
I feel that Vlad is justified, even if I personally would've just considered it to be a lost cause and just kept receipts in case it became necessary to publicly respond, similar to how the Apollo dev released receipts when Reddit tried to make him out to be in the wrong.
