"The right to be forgotten" is nothing more or less than the right to have some control over your identity, and over the ability of third parties to leverage that identity for their own ends. To argue that governments and companies should be forced or obligated to maintain long-term, fine grained surveillance for the sake of "history" is kind of absurd.
In any other context, HN would be up in arms over the same, with many going out of their way to exercise exactly that "right" through the use of anonymizing tools or proxies.
