Name a more free and open platform than the web. You can choose from any point in history.
The web is pervasive, secure-able by average users (and becoming moreso with Let's Encrypt), accessible in ways that no other Internet protocol is or ever has been, allows creation and participation by anyone of almost any technical ability or resources, it can be used anonymously, and, it has very low barriers to entry even if you do want to run your own site/server...much lower than any other Internet protocol.
I cannot think of a single piece of the Internet that is more open and free, for more people, than the web.
