That's surprising, I hadn't heard about that. I had assumed that this was a blanket rule that generally applied to these treaties. I wonder how the UK justified it...

Also, one other differentiator here is that the man, as you described him, was a French citizen. The post up above implies extraditing foreigners from their countries of residence to the US, which is on a whole other level of insanity. Imagine what would've happened if France tried to extradite a Scottish man from within the UK for online posts.
