Hard to take the analysis seriously when it (a) take UNIX as an example and (b) pretends Linux doesn't exist.

The Linux kernel looks to be a successful Bazaar project with a single person (Linus) having nominal responsibly.

I recently return to UNIX after a 20 year break. Linux in 2020 is much better than Solaris in 1998. However, Windows made giant leaps as well. Both still have massive amounts of deadwood but Windows does a better job of hiding it.
