There is an assumption that everything in the world should have 10ms latency. Why? Borders have always been meaningful to protect unique people groups. Maybe the extra latency is a way to protect indigenous cultures and allow local solutions to compete with Facebook. There are indigenous people groups all over the world where governments have said "leave those people alone!" American tech companies have done FAR more to destroy local cultures than missionaries could have ever dreamed of. Just because you can doesn't mean you should. Ultimately where it's going is that to the degree Facebook can't buy off all the local politicians it's going to have to follow the local laws and have unique policies for each jurisdiction. Ideally you would just have local companies running the social network, enforcing local norms, with federated APIs to communicate globally. Unfortunately the tech companies already control so much media and mindshare they are gonna probably keep that from happening in most places.
