I'd actually like to see a breakdown of IEEE costs. AFAIK, IEEE offers print-editions of several of its journals. I don't know who reads hard copies of journals these days, but I'm sure printing on actual physical paper would add to operating costs.
To the tune of a hundred million dollars? I can’t even remotely imagine how. If someone asked you to design a system to do all of those above things, would you actually come to the conclusion it’d cost a cool hundred mil yearly to operate?
