Most of this is because the people you are talking about don't actually use a computer to access the internet. They use a mobile computer. Mobile computers don't have the networking or energy storage (due to radio usage) capabilities to be able to participate in the internet as an equal. They almost all don't have a routable ipv4 and for those ones that do have ipv6, often it doesn't come with control over ports. If these people were accessing the internet from a home computer they could just install a simple static webserver and put HTML files, jpegs, gifs, etc in a folder, forward ports on their router, and bam, they're on the web.
