I would go one further. The *web* does not need to be Turing complete, nor does it need to support e-commerce. That is why we have operating systems, relational databases and GUI clients.
All of that existed and worked via TCP/IP *before* Java, JavaScript, and Windows 95! Those are what you get when capitalists co-opt a public good like the World Wide Web and the visions of Tim Berners-Lee, Ted Nelson and Vannevar Bush.
