Yeah, how dare he try to promote his website and become a future millionaire. If by sleazy you mean smart and willing to do what it takes to carve out a comfortable life for yourself, then yeah, he's sleazy.
Apparently implicitly lying to your viewers and directing them to a site that benefits you without mentioning that is ethical to you. In contrast, I view it as unethical.
Ethical: check out this cool site I built.
Unethical: here's a cool site I found.
Admittedly, this is pretty small potatoes, but it's still sleazy.
