It looks like the project has been decoupled from Verily (based on my poking about on the website) and is hosted within Google (the project lead, Linus Upson, worked for both Google and Verily simultaneously; he was mainly an eng manager/project lead, but had some historical experience with biology in school). Linus played a critical role at Google and built an awful lot of goodwill with the leadership.

Linus's LinkedIn indicates debug moved from verily to google in Dec 2024 (I missed this at the time). Debug was always a passion project (unlikely to make a huge amount of money compared to ads, AI, and cloud) and Verily's transition to something that lost less money probably required them to move Debug back to Google.
