Seems to me like they priced the API to cash in on the LLM training data gold rush, and as a side-effect it makes third-party user apps infeasible. Oops.

They priced the API for LLM training and killing third-party apps is just a great bonus. If they wanted to retain third-party apps while protecting their revenue stream they could have simply created a new free API including all the ads. They deliberately chose to kill these apps.

You can throttle APIs so they are still useful for a human browsing content, but essentially worthless for scraping meaningful amounts of data.
You can also detect accounts that are displaying scraping behavior and block them.
