Each week, we review the week’s news, offering analysis about the most important developments in the tech industry.

Hi, I’m Jamie Condliffe. Greetings from London. Here’s a look at this week’s tech news:

Big Tech is listening. Listening in, certainly. But listening to its critics? Well, maybe a little.

One trend of the past few months that I’ve not addressed here in detail is the drip feed of stories about what big tech companies are doing with user audio — particularly words uttered to A.I. assistants like Alexa and Siri, ones sent via Messenger or directed at your Xbox. It turns out that Amazon, Apple, Facebook, Google and Microsoft have all been sending sound clips to third-party companies to have them transcribed.

This will surprise no one in Silicon Valley: Picking out information from those audio files helps improve the artificial intelligence systems that now underpin many of Big Tech’s products.

Still, it surprised users. And that’s really my main reflection on this news: It’s a reminder of Big Tech’s reluctance to embrace transparency. The companies rarely explain how data is being used and shared. “The main fear, I think, is that in opening a dialogue with users, they will become more paranoid,” said Max Van Kleek, an associate professor at Oxford University who works on human-centered computing.

But there is now, more than ever, pressure for this to change. And this week, we got a preview of how that could happen.

On Tuesday, Facebook introduced a new tool, called Off-Facebook Activity, that allows users to see the mountain of data held about them in browsing histories, gathered via “Login with Facebook” partners or the company’s tracking pixels, that sites and apps have shared with the social network. Users can also disconnect that data from their account, so Facebook can’t use it for targeted advertising.
