I think you're right about the motivation. But I also think it's wrong-headed.
They should lean into who they are: The biggest, baddest, most secretive government organization on the planet. THAT's their brand. That appeals to some and turns away others. But trying to pretend they're anything else will fail to persuade anyone. Those who are attracted to the truth about the CIA are likely to be turned off by this mass-appeal approach. And those who hate them are unlikely to feel differently based on this.
It's like the Freemasons: What makes them attractive to those who are interested is the secret nature of the organization. Trying to make the organization more friendly and open is counter-productive.
Lean into the mystique, gosh darn it. Very few "brands" genuinely and organically have that kind of mystery about them. The CIA, like them or not, definitely have it.
