A couple of "recipients" are noted as having sent the money back, and others may have done so. As artbrooks noted, no payments direct from companies are indicated; but there is also no real indication of how much of the donated money came from peasants down in the mines and how much was from "top brass."
While some PACs do strongly encourage donations to particular candidates (borderline illegally) for most PACs a donation to a candidate doesn't necessarily support the company view, or advocate for it.
a. la. Ceasar's wife: Those who try to justify something that looks bad may be assumed to be doing something that is bad - even if a miracle happens and it isn't. (I'm not a great believer in miracles.)
