Ads have gotten worse and worse overtime. Some websites are so stuffed with ads the performance of the website suffers. Then there are risks associated with ads when many have become malicious or used to track people. Then what is advertised can also be extremely questionable. Everything from useless products to addictive mobile games to harmful "health" products to crypto scams show up on ads.
I'm fine with some ads on free websites/service if they're not crazy but too many sites have gone nuts. I'm not ok with ads with paid services. Ads during shows/movies are a no go when I paid for them.
