Where it gets quantitative, the Wikipedia page seems to be talking about "R&D" in general, which is an accounting category that is much broader than "research". When Intel designs a new CPU or Boeing designs a new plane, for example, that's under the "research and development" rubric in these figures. But they typically don't publish much about it, and a lot of what they're doing doesn't have much to do with the kind of "research" we're talking about here.
Perhaps more relevant, though, very little research indeed is funded by subscription fees to scientific journals or conference proceedings or sales prices of academic books; journal and conference authors don't even get royalties, and neither do their institutions, and very few academic books make a substantial amount of money.
I don't understand why overhead is relevant; we're arguing about who the funding agency is, not how grants are structured. If the NIH has to spend 40% of their dollars on overhead so that their PIs have offices and library access, and so does the HHMI, how does knowing this allow us to more accurately compare the expenditures of the NIH and HHMI?
