I don't care if the guy who made my hammer is a Pastifarian I care how well the hammer hammers, I don't care if my accountant likes to dress up as a skunk and go to conventions demanding people address him by Sir Reginald Stinkington as long as he does a good job at my taxes.
In this case it seems the concern is that the company donated to an OS project that is headed by a guy whom you don't like.... That just seems like there are plenty of other problems to address in the world.
