As for my mental gymnastics, honestly it used to be to hide the terrible ads but these days I just don't care. Get a better business model if the last remaining non-adblocker users don't keep you in business.
YouTubers use Patreon or (the gaming types) are switching to Twitch and their subscription system. Ebooks and online course sites work well for the more instructional content. There's an alternative to everything currently supported by ads. Heck, I imagine a newspaper would do pretty well on Patreon now that I think about it.
Edit: Dug up an example of an ad I installed an adblock to stop. These[1] are the ads that ruined it for everyone, not the bog standard Google ads. Honestly though I'm not going to the effort of checking each site's ad-worthy-ness anymore. All blocked.
