Your right, scraping is legally protected. It's reproducing verbatim text that's a violation, which is why LLMs still clumsily refuse to produce song lyrics. They are capable of copyright violations and have to be 'aligned' not to get their providers sued.

Verbatim reproduction is neither necessary nor sufficient to create a copyright violation.

"Copyright violation" is what we call the set of things that destroy the incentive for people to create original work by unduly benefitting from someone else's original work.
