Is there a way I'm not aware of to derive a private key from a public key? If I only ever give facebook my public key how the hell would they ever get my private key? Are you saying facebook hacks my home desktops to steal private keys?

If you read what denis-The-menace wrote, you'll see Facebook could ask users to give their private key to their (presumably closed-source) client, which could do anything with it. Responding with suspecting them of having some method of deriving the private key, or that uneducated users would really only give Facebook public keys, or Facebook hacking desktops does not address denis-The-menace's actual concern: public-key cryptography is very easy to exploit when the user-base is uneducated in its use, and Facebook offering such a new service to the masses is exactly the path one would follow to inspire users to feel secure all the while sabotaging them.

I am not sure I agree with denis-The-menace, but I wanted to point out that you didn't actually address his actual concern.

I don't know. I don't need to decrypt anything. The television I watch is unencrypted. I don't pay anything per month for renting hardware or subscribing to channels which are already beamed through my home.

I used to pay for cable channels which, to make room for more internet bandwidth, were further and further compressed every month until compression artefacts were so common as to be distracting. It wasn't long before the service they were providing, which was getting worse over time, was not worth the cost they were asking, which was getting worse over time. That was ten years ago now.

But when you call for a cab, they collect your number and location, and since they do this for everyone, pretty soon they have about as much information. And when you pay that single time with a credit card, bam - it all gets connected to a name. Without any privacy policies attached, not even a toothless one.

A taxi company knowing my phone number and location of pickup and location of drop-off is not "about as much information" as having my spacial coordinates and contact list at all times. Not even the same order of magnitude.

Your lament over taxi companies not having privacy policies is kind of odd. First, such policies protect the company, not you. Second, taxi companies have to follow rules, many of which cover privacy, which Uber flaunts.
