I find it difficult to take this too seriously, because Ad-Blockers already exist, are free, easy to install/use and work reliably (which is not given when ads could just be injected at the source).
The interesting question is that on the majority market, smartphones, they're very far from readily available - Firefox on Android, or basically nothing on iOS (see Epic discussion).
An AI device that slurps content and removes the ads is probably going to run smack into Apple content policy again.
