In a bid to avoid losing access to the cash cow that is your daily browsing data, ISPs like Comcast have been lying about Google and Mozilla's quest to encrypt DNS data. The effort would effectively let Chrome and Mozilla users opt in to DNS encryption -- making your browser data more secure from spying and monetization -- assuming your DNS provider supports it. Needless to day, telecom giants that have made billions of dollars monetizing your every online behavior for decades now (and routinely lying about it) don't much like that.

As a result, Comcast, AT&T, and others have been trying to demonize the Google and Mozilla efforts any way they can, from insisting the move constitutes an antitrust violation on Google's part (it doesn't), to saying it's a threat to national security (it's not), to suggesting it even poses a risk to 5G deployments (nah).
