Does xcancel scrape twitter? Isn't it more like a proxy for specific user requests to view tweets?

Correct, and nothing wrong with that.

It's almost as if moral values aren't assigned universally.

No one is upset that the AI companies are scraping the web, they’re upset how poorly implemented the scrapers, but the scraping itself is fine. Lots of people and businesses scrape the web.

Yes, anything that potentially costs Elon Musk money is objectively a good thing. :)

Yeah cuz X is fucking shitty, why would I want to give them any traffic?
