I'm not sure companies view it that way, and especially not companies like Facebook, whose product is the people who use their apps. As long as the person demonstrates he will use the product in spite of his problems with it, his opinions actually mean very little.

Think of it like a politician might: once you've donated to his campaign he has no incentive to give a fig what you think.

Of course people with lots of clout and wealth are special cases and the above don't necessarily apply to them.
