I have mixed feelings on this.
Many websites (especially the bigger ones) are just businesses. They pay people to produce content, hopefully make enough ad revenue to make a profit, and repeat. Anything that reproduces their content and steals their views has a direct effect on their income and their ability to stay in business.
Maybe IA should have a way for websites to register to collect payment for lost views or something. I think it’s negligible now, there are likely no websites losing meaningful revenue from people using IA instead, but it might be a way to get better buy in if it were institutionalized.
