Sam Altman returns to OpenAI, Apple adopts RCS, and Binance’s CEO pleads guilty to charges

Hey, folks, welcome to Week in Review (WiR), TechCrunch’s regular recap of the past few days in tech. The headlines have been dominated — nay, overwhelmed — by the drama unfolding at AI startup OpenAI, but plenty else happened in the half-week leading up to Thanksgiving. So much for a sleepy pre-holiday!

In this edition of WiR, besides the OpenAI saga, we cover Apple finally bringing RCS to iPhones, a former Silicon Valley VC darling being convicted of investor fraud, Cruise co-founder Kyle Vogt resigning and Amazon selling cars online. Also on the agenda is Elon Musk’s lawsuit over claims of hateful ads on Twitter, Google’s secret deal with Spotify, Binance’s CEO pleading guilty to federal charges, and Signal detailing the cost of keeping its private messaging service online.

It’s a lot to get to — so we shan’t delay. But first, a reminder to  After a roller coaster of a weekend and change, Sam Altman, who was CEO of OpenAI as of Friday morning, is CEO once again. The board of directors who fired him came to realize, eventually, that terminating him perhaps wasn’t the best course of action — after immense pressure from the OpenAI rank-and-file, VCs, close partner Microsoft and one of their own. For a play-by-play of how it all went down, check out our Mike Rothenberg, an ex-VC known for hosting lavish parties, was convicted late last Friday on 21 counts for defrauding investors. The verdict, delivered by a jury in Northern California, bookends a 10-year journey for Rothenberg, who burst onto the Bay Area scene in 2013 at age 27 with a $5 million fund and enough charm to persuade TechCrunch that his one-man firm was special enough to .

 A Google executive said during testimony in the Changpeng Zhao, also known as “CZ,” the founder and CEO of Binance, is stepping down and has pleaded guilty to a number of charges brought on through the Department of Justice and other U.S. agencies. The world’s largest crypto exchange, Binance has agreed to pay about $4.3 billion to resolve the DOJ’s investigations, the agency said in a press release late on Tuesday.

End-to-end encrypted messaging app Signal has put out an interesting overview of the costs required to develop and maintain its pro-privacy systems that shield user data from tracking by default. The , penned by Signal president Meredith Whittaker and developer Joshua Lund, reveals that the firm currently spends around $14 million per year on infrastructure to run the private messaging service and a further $19 million per year on staff costs. That totals $33 million to keep the lights on.

With Thanksgiving happening this week, mayhaps you’re in need of podcasts to muffle the sound of inter-family kerfuffles and sportsball games. (I know I am.) Fortunately, TechCrunch has plenty in its stable to choose from.

Equity published two — count ’em, two — episodes this week. The first recaps OpenAI’s wild weekend, from the firing of Sam Altman through the latest activity (as of November 20). The second — featuring former Equity host Matthew Lynley, Alex and yours truly — considers what the latest OpenAI twists and turns may bring for startup founders.

In her words: “If this company structure gives you the ick, you’re not alone.”

The companies that chose a flexible approach over depending on a single AI model vendor must be feeling pretty good after all the OpenAI drama, Ron writes. If there’s any objective lesson to be learned from all this, he says, it’s that it’s never, ever a good idea to go with a single vendor.
