As the last tech era consolidated into a small number of powerful aggregators, users have learned that many valuable services should be free.

The user will have to trust the incentives of whoever pays for their LLM completion costs.

If the paying entity primarily makes money from advertising, it will be hard for users to ever fully trust any advice the system gives them.
