From my experience, any business beyond a certain size ends up requiring scraping to get access to some data that is not published cleanly or available programmatically. It is also one of the common gateways to programming - and hence gets written more about I guess?

"I want piece of information from page programatically but there's no API."

Common ask, especially in anything dealing with secondary markets (card balances, information on sales, shoe drops, etc)

API will be much faster, but there's a place for this.

This is also common when talking to IVR systems (ex. I want a card balance, have some code call the phone number on the card, walk through the phone tree, and use voice reg to get the number)
