Xfinity, a Comcast affiliate, participated for the first time as an ISP in Mozilla's privacy measures
Mozilla is promoting the use of DNS encryption for privacy protection and is promoting the 'Trusted Recursive Resolvers (TRR)' program. For the first time as an Internet service provider (IPS), it was announced that 'Xfinity', a subsidiary of the major telecommunications company Comcast, joined the program. Comcast has a history of lobbying against DNS encryption, and Xfinity's participation is likely to be significant.

In 2017, Mozilla has begun to develop DoH (DNS over HTTPS), which encrypts DNS connections by browsers, ahead of this trend. In 2018, we were able to test it, announced the official implementation in September 2019, and decided to enable the feature by default in 2020.
On the other hand, based on the idea that DNS encryption by DoH is only half of the problem, and the rest is on the side of the DNS provider that can abuse DNS data, Mozilla is ``data restriction'' that stipulates that the DNS provider holds confidential information , 'Trusted Recursive Resolvers' program that requires 'transparency' that promises a clear policy, and 'blocking and correction' that prevents providers from censoring. Participating in this program are NextDNS and Cloudflare, who agreed with Mozilla's attitude.
On the other hand, ISPs are concerned about the movement of DNS encryption, and it is reported that Comcast, which is a major company, was developing a lobbying activity that interferes with Google's DoH promotion plan.
