The whole structure has changed. We are not even in the web 2.0 anymore and regressed to a client-server model where what we see is dictated from central platforms with little interaction between actual users.

This was not a natural evolution of the web but the consequence of low-tech people accessing the web passively via a tiny touchscreen.

More like a consequence of capitalism, as big tech companies used their massive capital to instrumentalize and develop knowledge to keep mostly everyone dependent and addicted to their systems. Due to the way capitalism work, when a push back against it through public policies was staged, they bought their way out of regulation of their toxic platforms and were allowed to retain their monopolies.

There are pockets of this on the internet, but you really have to go out of your way to find it

The central platforms began before smart phones were common.

Tragedy of the Commons. It was around 2012 when my reactionary boomer relatives started trying to friend me on Facebook, wondering what the kids were all talking about.
