I offer to my family VPN connection to my RaspberryPi which uses PiHole as DNS level adblocker. They seem very interested until I mention that I have possibility to see which websites they are visiting and they immediately seem uninterested, logically. I explain them that whatever DNS provider they use can see that data too and they don't care much about it. Anyway I recommend them to use Blokada and wonder why they don't trust me more than some shady ISP DNS :(
