I never quite understood that.


Not really all that difficult to understand.

The Koch Bros (a.k.a. The Dark Money Lords) throw small amounts of money a few legitimate causes ( including "The David H. Koch Fund for Science" - a major funder of NOVA on PBS - pretty amusing for climate change deniers and the billions they've spent to deny global climate change) to distract attention from the other shitty causes they pursue and fund and leverage and bribe politicians behind the scenes to the overall detriment of humanity.

The modern version of John D. Rockefeller teaching Sunday school while he raped his workers, destroyed competition by any means necessary, and murdered union members en masse.

Some people are apparently easily gulled & are unable to see thru the smokescreen.
