PSA: Buy a $30 thin client from eBay. Install Ubuntu (or your distro of choice), then install and set up pi hole, then use premade ad lists to block amp links (and whatever else you want).
Because a pihole doesn't stop people from sharing AMP links, it only prevents you from viewing them. So it's probably not a good answer to give when someone recommends that other people not use AMP links.
Don't get me wrong, a pihole is good to have for anyone who has the competency to set one up. They're not the answer to stopping people from sharing AMP links, is all.
