Well, it's generally frowned upon to pass off someone else's work as your own. Hell, he wrote an entire blog post detailing the process of 'building' this website (linked above).

It's staggeringly brazen. The only true sentence in his post is "It makes me look like I'm doing real work".

Oh hmm yeah, the blog post is a bit dishonest.

No, it's wrong because it is wrong. Not because whether someone benefits or loses because of it. That doesn't matter.

"Right" and "wrong" can often be quite an over-simplification as well as cultural (among other things)...

But I also clarified things in a sibling comment.
