Did you actually read that comment? I think the point is very clear -- given a reasonable price, people may would want to use the API instead of scaping the data themselves. If you instead ask for exorbitant amount of money, it only forces people to scrape, because there is no business model that would make it possible to pay.

I'm not going to pay $100 just to fetch 3000 records for a hobby project. I'll either skip the project, or I'll just abuse my scraping tool.

If they'd made some more reasonable pricing tiers, I would have been happy to pay.

Fetching something as simple as the total follower count from an API shouldn't be more (exorbitantly) more expensive than fetching data from, say, GPT-4. No reasonable person can make an argument for $10c/call pricing.
