While I can certainly see this upsetting some people, I'm not sure if this is necessarily "bad".

Web 2.0 was Yahoo Pipes, public APIs, IFTTT, etc. while this new "Web 3.0" acknowledges that those capabilities would rather be gatekept behind AI instead of entirely removed.

At the very least we do get some of that functionality back without resorting to scraping anymore and it's now accessible to the layperson. I would think this would nudge the layperson to demand more and inevitably want the actual data without the training wheels or sandboxes. Is that not a "good" thing?

Is the pushback against this out of genuine concern or just ideological?

Web 3.0 was very famously empty blockchain promises. I guess that makes this Web 4.0?

No, Web 3.0 was the Semantic Web: https://en.wikipedia.org/wiki/Semantic_Web

Apologies, I had my definitions mixed up!
