I have zero firsthand knowledge - so this is just rank speculation.
This does not smell like strategy to me. This smells like some USAF bubba has a budget meeting coming up and says 'dammit, we need to drop one of these things or this program is going to lose funding.' They run it up half the flagpole, nobody kicks, so they rock out. It makes news in the middle of the rest of the circus and folks at the top just say 'whatever, I've got other shit going on, tomorrow's tweet is going to top this thing.'
I just find it hard to believe it's part of some strategy to 'get tough' or send a message - and there was little to no PAO rollout before or after the drop.
Ladies and Gentlemen, with this post I pass the torch and title of Shadowspear Cynic to Ill Duce, long may he reign.
