Alex Stamos, Facebook’s former chief security officer, who left the company this summer to take up a role in academia, has made a contribution to what’s sometimes couched as a debate about how to monetize (and thus sustain) commercial end-to-end encrypted messaging platforms in order that the privacy benefits they otherwise offer can be as widely spread as possible.
Stamos made the comments via Twitter, where he said he was indirectly responding to the fallout from a Forbes interview with WhatsApp co-founder Brian Acton — in which Acton hit at out at his former employer for being greedy in its approach to generating revenue off of the famously anti-ads messaging platform.
Both WhatsApp founders’ exits from Facebook has been blamed on disagreements over monetization. (Jan Koum left some months after Acton.)
In the interview, Acton said he suggested Facebook management apply a simple business model atop WhatsApp, such as metered messaging for all users after a set number of free messages. But that management pushed back — with Facebook COO Sheryl Sandberg telling him they needed a monetization method that generates greater revenue “scale”.
And while Stamos has avoided making critical remarks about Acton (unlike some current Facebook staffers), he clearly wants to lend his weight to the notion that some kind of trade-off is necessary in order for end-to-end encryption to be commercially viable (and thus for the greater good (of messaging privacy) to prevail); and therefore his tacit support to Facebook and its approach to making money off of a robustly encrypted platform.
Stamos’ own departure from the fb mothership was hardly under such acrimonious terms as Acton, though he has had his own disagreements with the leadership team — as set out in a memo he sent earlier this year that was obtained by BuzzFeed. So his support for Facebook combining e2e and ads perhaps counts for something, though isn’t really surprising given the seat he occupied at the company for several years, and his always fierce defence of WhatsApp encryption.
(Another characteristic concern that also surfaces in Stamos’ Twitter thread is the need to keep the technology legal, in the face of government attempts to backdoor encryption, which he says will require “accepting the inevitable downsides of giving people unfettered communications”.)
