Absolute Zero: What if Facebook existed in the 18th century?

This might be a comic, but it deals with a more serious issue - about FB privacy. Is Facebook justified in using our private information to sell ads? Now FB is looking to create an ad network - so ads will be targeted to us through other sites, using our FB information!
Is this outrage-worthy?
Before you storm about how Facebook is trespassing on our privacy, consider these two points:
1. You don't pay for Facebook. It's free. Someone has to pay for all those servers. And really, do you have the right to complain about something until you pay for it?
2. You can always choose the amount of private information you put up yourself on Facebook, or any other site for that matter.
Discussions, debates, thoughts and of course, critique for the comic itself welcome! 😉
