Granted, I'm also a little surprised that the FBI didn't just twist Google's arm about it, but who knows. Maybe Google did them a solid and doesn't actually charge for the ad space, or maybe the FBI is just trying to play nice since Google has plenty of federal contracts.
Just twist their arm? What does it mean for the FBI to twist Google's arm?
What I was trying to convey was that the FBI could have exerted some kind of pressure to get Google to run the anti-booter ads of their own volition instead of the FBI (presumably) buying the ads like anyone else would buy ads. I have no idea what that kind of pressure would entail cuz I don't work for the feds and couldn't say what their "do this or else" strategies are like, lol.
I think that you are making an assumption about how the FBI operates.
Surely it's obvious that by "pressure" I'm referring to the threat of some sort of nebulous legal-y action if Google didn't comply with [xyz request]. Is that not how law enforcement functions? (I'd be shocked if they were asking very nicely and offering to take Google out to dinner.)
