From my story for Wired about Google’s new encryption plugin for Chrome “End-to-End“:
Google won’t be able to scan encrypted email messages in order to target advertising. Security expert Eleanor Saitta believes this may lead to Google to discourage most users from actively using encryption. She worries that the End-to-End may simply be a publicity stunt designed to keep Google’s engineers happy while scoring points with privacy advocates.
She also points out Google has history of abandoning projects that don’t make the company money, such as iGoogle and Google Reader. If activists come to rely on Google’s encryption tools, but those tools are discontinued, they will be left without crucial protections. “People live and die by the long-term success and failure of communication platforms — I mean that in a very literal sense,” she says. “You cannot put people in a position where they are depending on a software platform for life safety issues and then simply terminate it.”
Her other worry is that the existence of Google’s own plugin may discourage people from building other alternatives, or make it harder for open source encryption projects to raise funds. For example, Mailpile raised over $100,000 last year to build a new open source email client that works with any email provider, including Gmail, and has PGP encryption baked in from the beginning. But it will need more funding eventually, and Saitta worries that potential backers may not be as motivated to contribute.
