"Made for Adsense" sites have no value, if they get shut down, nothing is lost. Normal sites that switched to Adsense have become worse, because now they need clicks and engagement above all else, incentivizing click-bait and low-effort content. Nothing would be lost if they switched to subscription models and provided valuable content. There's little in between in my opinion, it's either "site doesn't use Adsense, it's a company site / personal blog / some institution", "site was made only to make money by adsense with the lowest price content possible, had a bunch of links bought and now provides a passive income to some SEO" and "site used to provide quality content, loses readership to spam-sites because Google has fucked up their sorting algos and now switches to low-value content as well, because anything else can't be financed".
Twitch shows that people are very willing to pay for content. I'd very much be happy to if that removed all of the spam.
