Never Give Up, Never Surrender

Done, somewhat; it's shockingly difficult to find emails or comment forms on most of these companies' websites. I managed Visa, Anheuser-Busch, and Molson/Coors, however, and I've found mailing addresses for Ford and Verizon that I'm off to use right now.

ETA: I should also add that the linked article in the twitter thread I found extremely helpful, both for info about the donations and for info to include in my emails/letters.
