At least in the US, getting the kind of home internet connection you’d need to support self-hosted content (symmetrical up/down, dedicated IP addresses, etc.) would require additional expenses, and broadband is already stupidly expensive for most people. Comcast, Verizon, AT&T, and most other residential broadband providers are all actively hostile to the idea of individuals running personal hosting services on non-business-class plans.
I also brought this up in a different thread about Facebook alternatives, but I don’t think it’s wise to ask people to take on the responsibility of managing network security for a device that’s actually supposed to be open to the outside world when there’s already a huge problem with those same people not being able to properly administer the multitude of devices in their homes that aren’t explicitly designed to be accessed by the entire Internet.
