There is a big difference between the Charlie Hebdo attacks and what Facebook is doing here. Charlie Hebdo wasn't legally censored. They weren't even breaking the law. They were just attacked by people who wanted to shut them up. One can support people's ability to say what they want without fear of mob violence and still not want to break the law.
It's about the crackdown following the attack. There has been various cases of people supporting (or seen as supporting) what the terrorists did being fined or condemned to prison.
> I find France's own crackdown on non-protected free speech during and shortly after their legendary march for free speech to be much more ironic than a business obeying local law.
I think you misread which comment I was replying to. That was the grandparent of my comment, while the one I was disagreeing with was basically saying that it was hypocritical of Zuckerberg to obey local laws after saying "Je suis Charlie." I don't think the idea "People shouldn't be killed for what they say" is necessarily incompatible with following local laws about what a Web service may publish.
