As I read it is basically says you can use Facebook's patents unless you turn around and sue them in which case the deal's off. I'm not sure it's that awful - I mean how many companies are planing to use Facebook's patents and then sue them?

You should read it again :) It requires no lawsuits to lose patents As written, if you make blog posts saying their patents are crap, you've lost.

(and the other provisions are not defensive, they don't require you sue facebook to lose patents)
