Alright Beerina - let's say that you're a Republican and you're upper-middle management at a company, or say, a large shareholder in the company.
The company decides to use its own funds to fund a book slagging the Republican candidate and promoting the Democratic candidate - wouldn't you feel as if the company resources were misused? That the place you're helping earn a profit (as an employee) or profiting from (as a shareholder) is using those funds to direct "speech" to a place you don't like as an employee/shareholder?
Perhaps I would think it an unwise course of action, but this is the decision of upper management, as hired by the shareholders/board of directors. As such, no, I wouldn't feel it was a misuse of funds. I reject out of hand that this would be done without the implicit approval of shareholders.
One of the modern frauds of politics is trying to define corporations as "non-entities" for the purpose
of criticizing government. The only thing worse than company money funding criticism of government is a government authorized to silence same.
Corporation or business = livelihood = survival. Are you feigning outrage that "how dare people trying to survive criticize government when it sticks it's clumsy, politics-driven ham hands into peoples' livelihood!?!??"
No, thank you.
Furthermore, implicit in your suggestion is the two-faced nature of most arguments about these kinds of subjects -- that one could,
indeed, should change a position based on "what's in it for me", and be damned any ideas of propriety.
It's a sad world some of you live in. I used to live there, too, up until about age 22 or so, so I know what you're thinking.
