The problem here is one of a corporation taking a community website and then systematically ignoring that community's input. We've seen it with the moves into business intelligence and the hell-or-highwater drive to beta. While a community website such as Slashdot is valuable to both its users and its owners, the relationship between the company and the community is asymmetrical.
There is relatively few effective mechanisms available to the community to have its will heard, short of simply leaving and never coming back (which defeats the point). Thus, concerned users are identifying the fulcrums around which this problem is revolving and applying leverage there to attempt to restore some balance between the goals of Dice and its user base.
While I agree that we should not be hassling private citizens outside their role as an employee, we are certainly at liberty to express our views and have them listened to. We're trying to save Slashdot's profitibilty, and by extension their employment, by ensuring that the website remains one that is attractive to its user base.
While the designer of the website is on the clock and responsible for the design and deployment of Beta, we are obliged to try to make them see that this is a terrible decision.
