What author misses is that multi-repo is also not dumbass proof. Our team of about 60 people owned about 5-6 git repos that compiled into one SO. Every simple bug fix required multiple diffs to multiple repos.

The real argument that the author is making is that worse is better. Monorepo requires good tooling and a disciplined team. Multi-repo is worse but it is easier to manage when dealing with inexperienced programmers who want to have their own repo for their shiny little microservice.

IMO, the difference is that multi-repo has limitations and mono-repo has challenges. You will never get atomic commits and precise versioning in multi-repo. With mono-repo, there are a lot of challenges that can be solved with good engineering.
