Just think how you'll feel if the SOPA or PIPA bills pass and there is no "Show my website anyway" button... 'Cause you can say that all you want, but if one of these bills pass and if the idiots deem it necessary, your content will get "darkened" regardless of how much money you paid to host it somewhere (maybe not the same way flickr is doing it, but still... to the same point).
I think everyones photos shouldn't be exempt, including the whitehouse photos! This is just a small taste of what is possible.
