I think you miss the point. Internet services are not the issue. The issue is the physical infrastructure which makes the internet possible. That physical infrastructure is still very highly centralized. The inter-links between countries even more so. It doesn't matter if diaspora exists or not as a distribute service. When a government cuts physical access to the internet to the internet by pulling the plug on the routers it controls and cuts physical access to cellphone networks it controls and cuts sat uplinks it controls... the existance of diaspora doesn't matter.
