Because a lot of current “AI” is a solution in search of a problem, being shoved into every product and hyped up as the next revolution, at a great expense. Even without the obvious environmental and financial impact, it is a huge nuisance. So people are upset and annoyed by it.

You could ask the same about pop-up ads, invasive apps, spammers, scammers, mandated age verification, Amazon’s treatmeant of employees, and so on. No one would defend bad choices made by powerful people.
