Well, we are an established publisher in the 14th year of our business and have been hit by panda on all our domains. The way I see it the more content and traffic you have the more likely you are going to fall a prey to Google's attack on the Internet. Most likely you are operating on keywords that people search for and bring the revenue and that is where the spammers play too. Also older domains are more likely to have techniques that were desirable at one time (remember how even search engines endorsed anchor text or linking to other websites or building directories, etc.?) but are now a reason for our downfall.
So it is not a conspiracy per se, it is just that the bigger and older you are, chances are you are more likely to get caught in one of the changed parameters in the algo.
