Honestly, it's hard for me to find websites that I regularly voluntarily use and do contain ads.
E-mail: Disroot (but with any provider that supports IMAP, you pretty much never have to visit their website)
Online shopping: while some of the sites may have ads, they could easily survive without ads because, well; they literally sell products
News: if HN stopped allowing links to websites with ads, I certainly wouldn't miss them
I'm not going out of my way to avoid sites that use ads, but I also don't feel obliged to enable their business model; that's their business, not mine. I care about controlling my own desktop.
Keep in mind that there is a lot of content out there that's funded by Patreon rather than ads. And I think the quality of Patreon-funded content is generally higher, because people consciously choose to support it, rather than it having to use clickbait and other dark patterns to lure your eyeballs in.
