This week we look at one aspect in which Chrome and Chromium differ, and then at a bit of growth news from the DuckDuckGo folks. Google's Project Zero reports on some terrific detective work, and we look at last week's Patch Tuesday. There's also Microsoft's pending change to the flaws which enabled last year's Zerologon debacle, and the NSA's interesting statement about enterprises and the DoH protocol. We look at the research that cracked the secret key out of Google's supposedly uncrackable Titan FIDO U2F dongle, and we catch up with a bit of listener feedback. Then we wrap up by looking at various aspects of the frenzy caused by WhatsApp's quite predictable move to incorporate its users' conversation metadata into Facebook's monetization ecosystem.
