Disabling ad blocking goes hand in hand with an "AI Browser" strategy.

Ad blocking relies on the ability to use filters to block network requests at the browser level, and visual elements at the DOM level. "AI Browsers" are designed to add bloat to the browsing experience, by offering to summarize something, or providing contextual information like say, a product recommendation that pulls data from a third party site. Network request and DOM element blocking would instantly negate that.

I've moved to Librewolf myself.

On the contrary, ad blockers and 'AI browsers' goes hand in hand. On one side is naive browser that displays pages as-is, on the other is user agent that shows what is relevant to the user. Ad blockers are just more static / more deterministic variants of that.
