I was once involved with a somewhat popular social network that was closing down, and some people in the user community would say this. It's not really practical, as there are lots of operating costs for hardware, bandwidth, looking after the domain names, DNS, security issues, DOS attacks, dealing with subpoenas from law enforcement, DMCA takedown notices, getting rid of illegal material, the list goes on. This work is difficult to do well, it's not the kind of thing that "developers in third world countries who get paid a pittance for basically busy work" can actually do successfully. The good developers in those sorts of countries are not doing busy work, they're starting their own social networks or migrating or doing the other things that good developers do.
