This is spot on and a big problem. And although nobody here including me would shed a tear about Facebook in this case, I am worried about the precedent this sets. Facebook has the deep pockets to either build this through or fight it legally to the bitter end. But for any startup trying to build a global X, this can put a serious blocker in the way. Global sharding of entities and working with that isn‘t for the faint of heart. I know we‘d stand still for a year or two trying to implement something similar as a small to mid sized startup. Philosophically and as a user, I actually like the idea, but wearing the systems architect here, this requirement scares me to no end and could throw a literal wrench into the operations of any global effort.
