The content of the propaganda isn’t why they’d be inclined to mask their involvement in disseminating it. You’d find similar content, with some value adjustments for the audience, from literally any regime in any political system. The reason they didn’t want to be attributed was because the value of the propaganda effort is making it seem (or become) organic. There are values expressed in Navy ads I find appealing, but I also recognize those ads are targeting potential recruits. I’m more likely to take expression of those values seriously when they’re expressed by unaffiliated human people. Or even my friend who is a naval officer but isn’t particularly inclined to shill for them. I’m certainly not going to take them seriously from a military-sponsored astroturf campaign.
