Many thanks to @blakestacey and @YourNetworkIsHaunted for your guidance with the NSF grant situation. I've sent an analysis of the two weird reviews to our project manager and we have a list of personnel to escalate with if we can't get any traction at that level. Fingers crossed that we can be the pebble that gets an avalanche rolling. I'd really rather not become a character in this story (it's much more fun to hurl rotten fruit with the rest of the groundlings), but what else can we do when the bullshit comes and finds us in real life, eh?
It WAS fun to reference Emily Bender and On Bullshit in the references of a serious work document, though.
Edit: So...the email server says that all the messages are bouncing back. DKIM failure?
Edit2: Yep, you're right, our company email provider coincidentally fell over. When it rains, it pours (lol).
Edit3: PM got back and said that he's passed it along for internal review.
