I think that's actually the point. when evil big company threatens to destroy little guy, it always makes great headlines regardless who is right and before you blink, he will be selling thousands of posters a day.
Since you are likley to get a C&D, I would prepare with an alternate domain name and a list of bloggers who are anti-facebook. Calcanis comes to mind. Send out a press release about the C&D, how FB is trying to control users images, and all the privacy/control of content issues. Once the media storm has whipped itself into a frenzy, then announce the new website name and redirect the original.
I guess you're getting downvoted because of the 'ethically questionable' suggestions you're making. Strictly in terms of making profit, I think you're spot on.
good call! do you know about putting out a press release? also let me know if you think of any more anti-facebook blogs. Thanks for the input :)
