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.)
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.
