> Comcast sniffs / records / tracks their user's DNS traffic
Actually not only does Comcast say they don't do that (https://www.xfinity.com/privacy/policy/dns) but now has signed a contract to this effect as well, thereby meeting the same level of commitment as the other TRR operators. This means IMO that Mozilla is doing a good job leading the industry on DNS privacy and convincing many of the merits of a strong pro-privacy philosophy.
