Good morning.

On Tuesday, months after Senator Elizabeth Warren of Massachusetts first unveiled her proposal to break up Facebook and other tech giants, The Verge published highlights from two hours of leaked audio in which Mark Zuckerberg railed against Facebook critics, competitors and Ms. Warren.

Our political correspondent Matt Stevens covered Ms. Warren’s response to the remarks:

Remember that giant billboard near the Caltrain station in San Francisco? The one with Senator Elizabeth Warren’s face on it? The one that said in all capital letters: “BREAK UP BIG TECH”?

With Ms. Warren seeking the Democratic nomination for president, her campaign put up that billboard over the summer after she rolled out her plans to regulate the tech industry. One needs only to look to the billboard for evidence that she wanted to make very sure tech workers got her message.

On Tuesday we learned that, yes, in fact, they did get the memo — and that at least one of Silicon Valley’s power players is not a fan.
