Porn and Edge

Edge circumvents local DNS. I put 1.1.1.3 and 1.0.0.3 in the local network interfaces and the router and the cablemodem. Chrome and Firefox won't let the 3rd graders surf porn, but Edge empowers 3rd graders to surf porn! What is the real purpose of this? Limited choices in Edge config for private dns i.e. 1.1.1.1 (no filter) is allowed but 1.1.1.3 (no porn/malware) is not allowed (as of last night). Sure is suspicious to those of us who argue against crimeware and child exploitation... and who are trying to protect the children (et al).
