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

Is your data worth $5 a month to tech companies? $20? More? How much would make you care?

An answer to the final question may come from a bill proposed by Senators Mark Warner, Democrat of Virginia, and Josh Hawley, Republican of Missouri. Their bill would require companies that collect user data to tell consumers and regulators what they collect, how they make money off it and how much it’s worth — in aggregate and broken down by users.

“The overall lack of transparency and disclosure in this market have made it impossible for users to know what they’re giving up,” Mr. Warner said in a statement.

Which is true. Seeming to acknowledge such concerns, Facebook announced changes to its terms of service a few days later, explaining how it makes money. “Business and organizations pay us to show you ads,” it said. “We use your personal data to help determine which ads to show you.” (Unbelievably, it hadn’t said that before. Sorry, you expected more?)
