The issue here is not whether Anonymous activists can be rightfully prosecuted: acts of civil disobedience, by definition, are violations of the law designed to protest or create a cost for injustices. The issue is how selectively these cyber-attack laws are enforced: massive cyber-attacks aimed at a group critical of US policy (WikiLeaks) were either perpetrated by the US government or retroactively sanctioned by it, while relatively trivial, largely symbolic attacks in defense of the group were punished with the harshest possible application of law enforcement resources and threats of criminal punishment.
That the US government largely succeeded in using extra-legal and extra-judicial means to cripple an adverse journalistic outlet is a truly consequential episode: nobody, regardless of one’s views on WikiLeaks, should want any government to have that power. But the manifestly overzealous prosecutions of Anonymous activists, in stark contrast to the (at best) indifference to the attacks on WikiLeaks, makes all of that even worse. In line with its unprecedented persecution of whistleblowers generally, this is yet another case of the US government exploiting the force of law to entrench its own power and shield its actions from scrutiny.
