So, maybe eventually. They found that Git didn't do well at their scale, so they modified mercurial instead.
I'm all in favor of a company-wide mono-repo if it doesn't have scaling issues.
I don't think anyone in this thread is CTO of a company size of Facebook. For a medium size company, you can easily use Mercurial or Perforce.
