As of this writing, MCD, SBUX & PEP continue to operate in Russia.
I've decided to contact them to express my deep concerns regarding their continuing to operate there. the form letter I used is below. This is just FYI.
"Many companies recognize that doing business with Russia right now is tantamount to supporting war against Ukraine. I urge (NAMED COMPANY) to take a humanitarian stand and refuse to do business with Russia so as to be a part of stopping the violence against innocent civilians, including children. Nobody wants to be listed as one of the companies that put profits over the lives of innocent children, and the public is paying attention to what companies are doing. I know (NAMED COMPANY) takes its corporate social responsibility seriously - now is the time more than ever.
Do the right thing. Exit Russia. Immediately!"
