Glad you pinpointed the important bit rather than the lie about caring about privacy
i.e.
"The Chrome Web Store policy changes coincide with a related effort, Manifest v3, to revise Chrome extension APIs so they're less powerful – making them less suitable for abuse but also less useful for content blocking."
Still, it will drive more people to pi-hole, 60K+ host files (based on the one I use for ad blocking) , proxies with url filtering or similar if ad block extensions no longer work on chrome.
