This is incredibly sad, with google you can atleast use the argument that search was free (which is still weak IMO). But with OAI collecting indiscriminate data on paying customers is just incredibly sad.
The ads are the product that people are paying for. “Consumer” AI is currently marketed as agents that book restaurants for you, buy cat food before you run out, organize your travel, etc. etc. These are targeted ads for a particular restaurant, pet store, airline, etc. Some people find this desirable.
