Josef Bacik who is a long-time Btrfs developer and active co-maintainer alongside David Sterba is leaving Meta. Additionally, he's also stepping back from Linux kernel development as his primary job.

Josef Bacik had been employed by Meta working on Btrfs for years. Unfortunately, that time is coming to an end. Bacik [1]announced today:

"Today is my last day at Meta. This has been the best team I’ve ever been on, and I’ve been on some great teams. Next week I start a new chapter, I will be joining Anthropic to help them scale out their infrastructure and put my decades of kernel and systems experience to use. I will be stepping back from kernel development as my primary job for the first time in my career. I’m sad to leave my colleagues, but I’m excited to try something new and see where it takes me."

So he's leaving Meta and Linux kernel development at large for the Anthropic AI start-up.
