I doubt this will do anything, but it would be nice if it did. Really bad people should be shunned:

Dozens of climate scientists and environmental groups are calling for museums of science and natural history to “cut all ties” with fossil fuel companies and philanthropists like the Koch brothers.

A letter released on Tuesday asserts that such money is tainted by these donors’ efforts to deny the overwhelming scientific consensus on climate change.

“When some of the biggest contributors to climate change and funders of misinformation on climate science sponsor exhibitions in museums of science and natural history, they undermine public confidence in the validity of the institutions responsible for transmitting scientific knowledge,” the letter states. “This corporate philanthropy comes at too high a cost.”

The letter does not mention specific companies, but it does name David H. Koch, who sits on the boards of the American Museum of Natural History in New York and the Smithsonian National Museum of Natural History and has given tens of millions of dollars to those institutions.

Koch Industries is a privately held corporation with subsidiaries in energy and other industries. Mr. Koch and his family have funded conservative causes, including scientists and organizations that contest the role of humans in climate change.
