There is a non-zero chance that the message encrypted in the genesis block is a regular timestamp with a headline from the first fresh newspaper Satoshi came across to document that the bitcoin network was launched no earlier than January 3, 2009.
Of course, the early cypherpunk movement was thoroughly imbued with romantic rebellious spirit of protest against the existing financial system. But is it necessary to look for hidden political subtext here? If Cypherpunk is considered a political movement, then it is a political movement against politics, in a sense it is anti-politics, a protest against the dominant role of politics in our ordinary daily life. At least that's how I understand it.
Maybe this is just a funny and quirky way to document the launch of the Bitcoin network by Satoshi who wanted to document the launch of the network in a memorable way and my take on the early cypherpunk movement was all about promoting privacy, decentralization and individual freedom and those values were reflected in the design Bitcoins themselves.
So it's not hard to imagine that Satoshi might want to make a statement about those values in the first place, but at least, that's how I see it!
