I guess they could effectively copy Kagi's model at mammoth scale - offering a premium internet browsing experience with a 'personalised assistant'.

Easy to convince at least 10% of the users to sign in to their browser with a verified credit card to 'protect the children', and governments around the world would give you full support.

At that point, would be trivial for them to track browsing habits, and then to start offering personalised assistants which save you time and eventually cost money.

Pretty sure you could save money throuh having a huge botnet of computers to tap into, and a huge amount of data to help cache and standardise common requests.
