Yeah. The NSA and the CIA doesn't care about WSWS, and Google simply made an editorial decision that these guys don't have a credible or objective view of history and shouldn't be a search result for neutral terms on history. How's that for a non-conspiratorial version?
But this "editorial decision" (ahem, "tuning") is in fact a political decision to downgrade results for a site that by any objective measure has a wide, international readership (Alexa global rank, 30-40k). It is also an objective fact that Google has close relations to the state (top federal campaign contributor, regular visitor to the White House, Eric Schmidt book praised by Michael Hayden, etc.). So it is a "conspiracy theory" that Google's actions might be motivated by political considerations? Of course, Google might think so... As for the WSWS, it was recently the subject of editorials throughout the German media for its campaign against Jorg Baberowski, a right-wing historian at Humboldt University who is attempting to whitewash the crimes of the Nazis. If you think that the WSWS is not getting the attention of the state, then you aren't following developments closely.
I think you mean that it's a conspiracy, and I think there are plenty of better explanations than Google working secretly with governments to promote capitalism.
