I think the author is confused or biased. Corporations cannot use corporate funds to make donations to political candidates. That's why PACs exist; and they are entirely funded by employees. I suspect that while a lot of its employees are left-leaning, (just like in the general population) there are some right-leaning as well, and the PAC cannot prevent those from making their donations to whomever they choose. Microsoft doesn't donate any of its own money to anyone (they would be breaking the law if they did). Microsoft employees do.
