Why Facebook does not use Git – and why most other devs do • DEVCLASS (devclass.com)

Facebook does not use Git due to scale issues with their large monorepo, instead opting for Mercurial.
Mercurial may be a better option for large monorepos, but Git has made improvements to support them better.
Despite some drawbacks, Git usage remains dominant with 93.87% share, due to familiarity, additional tools, and industry trends.

The source control was so smooth and pleasant that it convinced me that git isn't the be all end all, and the general developer focus was super nice, but some of that tooling was pretty janky, poorly documented, and you had no stack overflow to fall back on. And some of it (like EdenFS), really felt like it was the duct tape holding that overloaded monorepo together (complete with all the jankiness of a duct tape solution).
