Why should my computer have auditing capability, without my explicit knowledge or me making the decision to put it there? Who is it good for?
Someone who desires to keep track of a user's key strokes, for example a corporation. This is coming from someone who consents to monitoring every day.
While I agree it is not good for the singular, non-ignorant person, I'm sure there's a massive market for "Corporate Consumers" who'd like to save a buck instead of spending effort configuring a system.
About having the capability of auditing, I suppose it saves production costs to have one laptop with a switch, as opposed to two laptops with slight hardware or software differences.
