The perception is probably one of ownership - e.g. you think you own the "machine" you're using (and, by extension, its OS) but not the web site you're consuming. From that viewpoint, you don't expect websites to be acting in "your" best interest, necessarily, since they're not "yours" - but you do expect "your" machine to doso, or at least not actively act against it.
