If they have to build infrastructure to support reselling game use licenses to comply with this law, it's unlikely they'll be able to justify releasing it to France only; there'll be backlash from their users in other countries.
That sucks; glad I'm in the US because I use that feature often. It's great for when friends ask for the photos I took of them.
In any case, I predict the Steam situation will differ because privacy and retail goods are valued differently. Americans are going to want that feature if Steam has to implement it, and they have options regarding what game store they use; it becomes a point of competitive advantage for Steam to switch it on in the States. They'll have to do the calculus on whether they lose more potential developers if they do vs. lose more potential store users if they don't.
