Elon Musk is finally out as Twitter’s CEO. On Monday, his replacement—former NBCUniversal ad chief Linda Yaccarino—said she had taken over as the bird site’s chief executive.   

“It happened — first day in the books!” she wrote. “Stay tuned…”

Yaccarino has yet to speak on her new role, making it unclear how she intends on leading Twitter. But she now faces the tough task of luring advertisers back to the social media platform. The company’s ad sales recently plunged 59% year over year, according to The New York Times, when advertising generally makes up 90% of Twitter's revenue. 

On Monday, Musk himself acknowledged the business problems during a Twitter Spaces session with presidential candidate Robert F. Kennedy Jr. During the talk, Musk accused non-profit groups of pressuring advertisers to halt business with Twitter since it shifted priorities to promoting "free speech" over reining in content moderation.

This has included inviting banned users—including white nationalists—back to the platform, which has caused ads to appear next to their tweets.

“Basically, our revenue was cut in half because we didn’t tow the line,” Musk said. “And it’s frankly a struggle for Twitter to break even, and we’re hoping to break even, but we’re not there yet. But I don’t care how much it costs or what it takes. If we lose free speech we lose democracy.” 

Musk thanked companies such as Apple and Disney for continuing to advertise on the social media platform. However, he noted other advertisers have boycotted Twitter. 

“For North America and Europe, we’ve seen roughly half of our advertising disappear overnight simply because we insist on free speech,” Musk claimed.

Although Musk is stepping down as CEO, he’ll remain as Twitter’s owner and chief technology officer. So he'll continue to have a huge influence on the platform, which he acquired in late October. At this point, Twitter has lost about 80% of its staff through layoffs and resignations

My Experience

I've been a journalist for over 15 years. I got my start as a schools and cities reporter in Kansas City and joined PCMag in 2017, where I cover satellite internet services, cybersecurity, PC hardware, and more. I'm currently based in San Francisco, but previously spent over five years in China, covering the country's technology sector.

Since 2020, I've covered the launch and explosive growth of SpaceX's Starlink satellite internet service, writing 600+ stories on availability and feature launches, but also the regulatory battles over the expansion of satellite constellations, fights with rival providers like AST SpaceMobile and Amazon, and the effort to expand into satellite-based mobile service. I've combed through FCC filings for the latest news and driven to remote corners of California to test Starlink's cellular service.

I also cover cyber threats, from ransomware gangs to the emergence of AI-based malware. In 2024 and 2025, the FTC forced Avast to pay consumers $16.5 million for secretly harvesting and selling their personal information to third-party clients, as revealed in my joint investigation with Motherboard.

I also cover the PC graphics card market. Pandemic-era shortages led me to camp out in front of a Best Buy to get an RTX 3000. I'm now following how the AI-driven memory shortage is impacting the entire consumer electronics market. I'm always eager to learn more, so please jump in the comments with feedback and send me tips.

The Best Tech I've Had:

  • My first video game console: a Nintendo Famicom
  • I loved my Sega Saturn despite PlayStation's popularity.
  • The iPod Video I received as a gift in college
  • Xbox 360 FTW
  • The Galaxy Nexus was the first smartphone I was proud to own.
  • The PC desktop I built in 2013, which still works to this day.
