After all these posts, I still don't get what is the problem with the ISP seeing my DNS queries. That's still private telecom information protected by law. Unless you're doing something obviously illegal, and are under investigation. They can't do anything with that data legally. Using Cloudflare or VPN most likely won't solve the problem anyway, at least if you're doing something criminal enough. Therefore claiming it making you untraceable on net, is snake oil anyway.
