We have only the OP's word that this is actually what happened, and there's no way they could know that. The author also admits to having leaked their Discord key and accidentally leaving the GitHub repository public; their technical competence is in question here. It almost reads like a creative writing assignment. How would anyone have known he was about to register the domain?
I'm sure this did happen but given the followup post (https://kill-saas.com/posts/from-0-to-5) it seems like the author is mostly playing up the experience as a way to advertise his product. Mentioning the vibe coding, the Discord key, and leaving the GitHub repository public feels a little like this might be clickbait.
Definitely sleazy. Not sure if it's a good way to make money. People can just get a different domain name, like OP did. And a small project that's not paying for a closed github repo, is unlikely to shell out extra for their domain name.
For well-funded corporate projects it makes more sense; those cost more to rename, and paying extra for the domain name they want is nothing to them.
