I don't think wayne was attacking you specifically, but the notion of not putting a link at the bottom of a page, in general. Having a "powered by/made by/etc.." link at the bottom is actually pretty common for most small/medium sized sites. The only people who don't really do that is bigger companies, and they don't do that because they pay a lot of extra money to not have stuff like that. Which usually involves having everything custom made from scratch in the first place, because a lot of 3rd party stuff requires you to have a link, as part of the ToS/license.
