DNS isn’t the right place to attack this, IMHO.Are we sure that the filtering is done in the default view - I would suggest the user check to ensure they don't have a filtering service (e.g. parental controls/malware protection) turned on. In my **personal** opinion, the default view should have DNSSEC validation & no filtering; users can always optionally select additional protection services that might include DNS-based filtering as well as other mechanisms.
At Quad9 they are clear that 9.9.9.9 is filtered. Cloudflare 1.1.1.1 is unfiltered, 1.1.1.2 filters malware, 1.1.1.3 malware and stuff unsuitable for children.
I have no idea whether Charter uses one of these, some other third party, or their own. We must know someone there who could tell us.
