ISPs lied to Congress to spread confusion about encrypted DNS, Mozilla says

Mozilla is urging Congress to reject the broadband industry's lobbying campaign against encrypted DNS in Firefox and Chrome. The Internet providers' fight against this privacy feature raises questions about how they use broadband customers' Web-browsing data, Mozilla wrote in a letter sent to the chairs and ranking members of three House of Representatives committees. Mozilla also said that Internet providers have been giving inaccurate information to lawmakers and urged Congress to "publicly probe current ISP data collection and use policies."

DNS over HTTPS helps keep eavesdroppers from seeing what DNS lookups your browser is making. This can make it more difficult for ISPs or other third parties to monitor what websites you visit. "Unsurprisingly, our work on DoH [DNS over HTTPS] has prompted a campaign to forestall these privacy and security protections, as demonstrated by the recent letter to Congress from major telecommunications associations. That letter contained a number of factual inaccuracies," Mozilla Senior Director of Trust and Security Marshall Erwin wrote.
