A quick look at projects as huge as the Linux Kernel and its distributions (debian, arch, fedora), platforms such as kubernetes, apache, entire languages such as rust, python etc, databases (postgres, etc) shows this is nonsense.

Most of the internet is run on software built by geographically dispersed engineering teams working asynchronously. Software so well developed and innovative that companies as large and office based as Microsoft eventually had to back down and hop on the ride.
