This week on the GeekWire Podcast, we discuss Amazon’s efforts to compete with Trader Joe’s, and the related tactics revealed in “The Everything War,” the new book by Dana Mattioli of the Wall Street Journal. We also revisit last week’s episode with Mattioli and share some of the reactions to the discussion.

Plus, the FTC probes Amazon’s internal use of Signal’s disappearing messages feature, a newly disclosed email shows how Microsoft scrambled to catch up in artificial intelligence, and a new report says that Bill Gates is still a highly influential figure inside Microsoft, especially when it comes to the company’s AI strategy.

Finally, we go inside the Seattle courtroom where a prominent figure from the cryptocurrency world, Binance founder Changpeng “CZ” Zhao, received a controversial prison sentence this week.
