I agree with you, except I don't see a down vote button anywhere on this site.

But yes, generally, when a company promises to be your best buddy no strings attached it is time to get suspicious, and when someone believes them I begin to figure out if they're just naive or actually unintelligent.

Why don't I see down arrows?

There are no down arrows on stories. They appear on comments after users reach a certain karma threshold, but never on direct replies.

Just as an FYI, you need a certain amount of "karma" before you see the downvote button.
