I'm not sure what the deleted comment said but there is plenty of official reddit admins commenting in the linked thread

The comment looked at the relationships of the banned sites and their competitive nature with the other Condé Nast properties, and how they are in fact some of the biggest competitors to these said properties.

But reddit isn't owned by Condé Naste anymore: http://blog.reddit.com/2011/09/independence.html

Do you really think they are that out of touch with their capricious user base?

They would have to be barking mad to think they would benefit from trying to control the site in favor of Advance.
