have you ever heart that google is also one repo? at least it was until 2015. don’t know the story later. So it doesn’t have to be one person company. yet they are making billions
Google isn’t a monorepo since the acquisition of Android. That one never made it into google3.
I'm not making any claims about monorepo being good or bad and I'm fully aware large companies have monorepos (or at least very large repos). I'm saying that the fact it's a one-person "company" needs to be taken into account when talking about how applicable their experience is to other companies.
