The House sent a letter on September 13th asking if Google would use the data handled through the process for commercial purposes. Google has maintained that its Chrome tweaks will give users control over who shares their info, and that it will not force people to switch to encrypted DNS.
That likely won't allay telecoms' fears. Internet service providers are worried that they may be out of data and won't know much about their customers' traffic patterns. This could "foreclose competition in the advertising and other industries," an alliance of ISPs told Congress in a September 19th letter.
Google might not have much to worry about, though, as it's not the only one pushing for the same encryption. Mozilla also wants to use the format to secure DNS in Firefox, and the company's Marshall Erwin told the WSJ that the antitrust gripes are "fundamentally misleading." ISPs are trying to undermine the standard simply because they want continued access to users' data, Erwin said. Unencrypted DNS helps them target ads by tracking your web habits, and it is harder to find DNS tracking than cookies and other typical approaches.
