Both your mother and your aunt would be signing in to (name of decentralized social service).google.com, just like everybody else except for a handful of geeks who take pride in running their own nodes. Or Microsoft's node, or Yahoo's node, or Amazon's node or anyone else with the infrastructure to run a huge scale social site. But all that aside, you don't consider this a better situation than now, where all data is walled off and silo'd and the biggest player is an effective monopoly with much, much less interest in privacy and data security than Google? And geeks have no option whatsoever to operate a social network independently? If not, what do you propose, other than acquiescence?
