I'm a firmly bitter user who has stopped frequenting a lot of websites because they don't load well or don't give me what I consider to be an acceptable value prop (I'll happily turn off my adblocker if your ads are well behaved, I won't take a survey to read a one paragraph article).

But most users, and especially most non-technical users, aren't willing to take that same stance despite being very frustrated. It seems to vary between "well that's just how the internet is" to "I don't know any other sources". Having google prioritize non-terrible sources is a big boon to those non-technical users in my eyes, cemented firmly when I watch my mom or other older family members try to search the internet.
