I followed that link, and the post itself seems to not be that, no one in comments was pointing to anything that was a smoking gun on that, and someone else linked to the CEO directly saying that, no, absolutely not, it'd be bad business to do so.

Which feels weird to defend GoDaddy, because, while I haven't used them in a few years, my experience with them is that they're an awful registrar, but mostly because of how hard they make it to transfer away and how sleazy they get with sales tactics. And their ads haven't been... good, but I'd probably let that slide if they provided reliable, good service.
