Facebook's chief security officer Alex Stamos spent part of Saturday responding to critics who say it should overhaul its systems in response to concerns about fake news and foreign election meddling on the platform. His message, basically, was that it's complicated.

"I am seeing a ton of coverage of our recent issues driven by stereotypes of our employees and attacks against fantasy, strawman tech [companies]," he said in a Twitter thread. "A lot of people aren't thinking hard about the world they are asking SV to build." Read his comments in full below.

Why it matters: This is an uncommon level of candor for an executive at the secretive social media company as it faces questions from regulators and the public about possible Russian use of the platform to interfere with the 2016 election. Stamos is one of the public faces of the company's investigation into those issues.
