There are three groups of people who should have an interest in a given site:
A) The site owner, who wants it to get relevant traffic and generate business.
B) People who write online, and need new content to write about--especially if it's useful to their target audience.
C) Potential customers of A), many of whom are part of the target audience of B).
Now, it is in nobody's interest for A) to refuse to speak to B) on the grounds that C) will somehow find A) naturally.
I believe this guy was punished because his "experts" used paid links. Can you find a reference for the assertion that he was punished for hiring someone to help him rank well, or that Google believes in punishing such activity? Bear in mind that the head of Google's webspam team routinely speaks at SEO conferences, where presumably all of the attendees are in the results-gaming business. If your worldview is correct, that's really weird; like the CEO of Brink's making a habit of speaking at safecrackers' conventions.
