Agreed and advertisers do agree too. They themselves demanded controversial content to be removed while their ads are showing, society demanding the same is in line with that thought. They do pay for many internet services, but I think the negative aspects outbalance the monetary advantages.
I don't think this is necessarily true. They demanded that their ads are not shown next to controversial content.
An unintended consequence of this is that the definition of 'controversial' is fluid and open to abuse. So if a pressure-group deems your thoughts and opinions 'controversial' you get no ads. And if you get no ads there's no real incentive for YT or whatever to serve your content; they're not charities. Your only other option is to self-host. So advertisers and indirectly control the societal narrative, and that should be troubling.
