You do realize this breaks the ability of www.example.com to track its traffic? They have now lost the information as to how their search rank is performing on Google, and have acquired incorrect information that they think you typed in www.example.com directly.

You're entirely within legal rights to do this, of course. But if everyone did, then sites would have no idea where their traffic is coming from. Morally it is a bit questionable: your browser is blatantly and directly lying to www.example.com about how you got there.
