Websites that use CNAME to forward their main domain to some tracking company, basically give their entire domain away, I don't see how that is a good secure way to track your users..
DNSCrypt-proxy (and even pihole these days I believe) are actually capable of blocking forwarded CNAME requests. Setting up such system for network wide adblocking is not complicated at all, see: https://github.com/notracking/hosts-blocklists/wiki/Install-...
