If you are interested in the evolution of the Internet, you should read the RFCs from ARPANET. The RFCs started in 1969. They are clearly talking about dynamic read/write data.

If the W3C intended the Internet to be exclusively for static data; then why did they include the FORM element in the HTML specification? This the FORM Element Defined in HTML 2.0 in 1995. Apparently, HTML 2.0 was the first formalized definition of HTML.

Well that's of your view not of Tim Berners Lee the founder of the web view

I looked up the Wikipedia article on Web 2.0. It has an interesting paragraph that reads:

Whether Web 2.0 is substantially different from prior Web technologies has been challenged by World Wide Web inventor Tim Berners-Lee, who describes the term as jargon. His original vision of the Web was "a collaborative medium, a place where we [could] all meet and read and write".

Apparently Tim Berners-Lee openly refutes your claim. Yes, his very first example was static. But that is true of almost every program. The reason for this is that one has to create an authentication system before allowing writes.

Berners-Lee even calls Web 2.0 jargon. It was a marketing ploy. Claiming that the Internet before Web 2.0 was static is a demonstrable lie created by marketers for big tech selling people on centralized social media platforms.
