Several of those ideologies you mention are just different flavors of authoritarianism, and one of an ideological authoritarian's primary goals is power. Hell, take out "anarchist" and you could make a convincing argument they're all authoritarians in their own way. You don't get power by giving the populace - or helping them to keep - a free, secure Internet. It's just completely antithetical to someone who wants to hold power by nondemocratic means.
