IMHO it's outrage-bait from an AI researcher who is likely oblivious to the costs of the computing infrastructure they use and thinks the overhead being charged on top of the grant award is outrageous because they don't have lab space and such.
Sadly, most researchers have zero appreciation for how much computing infrastructure costs, and how they think it's perfectly fine to store data for a several million dollar research grant, that involves multiple people's academic careers, on a USB hard drive they got at Best Buy because buying a proper server etc would cost too much.
You can see their attitude in how outraged they seem to be about having to pay a grad student $46k a year...
