Sending a packet in response to some other packet
is something "a computer does". Back when "ordinary people" thought that witch-dunking was an "ordinary" security measure, "ordinary people" were wrong. Improvements came not when the courts surrendered to ignorance, but when they corrected it.
Very few "ordinary people" would describe websites as "places", anyway. They don't say they're "at" Facebook, they say they're "on" it, much like they could be "on the phone" or "on TV". Maybe this hasn't always been the case, but the courts aren't tied to 1990s-era metaphors. No one on a jury remembers those silly "Welcome to the BatCave, Come on in if you Dare" geocities pages.
Incidentally, Facebook and its ilk hold ordinary people to much more complicated standards of behavior than those to which you and they would hold sites, all the time. Oh, you didn't read all 50 pages of TOS and then update the (hidden) configuration, every week? Silly user, that's why we gave all your data to the English!
Meanwhile, you don't think Facebook should have to understand how HTTP works, just because one person working at the company might not. Interesting, that the benefits go one direction and the duties go the other.
