We're not talking about modern Linux though. Modern Linux isn't "coordinated by a (admittably singlularly competent) sole finnish guy in a bathrobe from home,", there's now a team of people involved. Sure there is a hierarchy with someone taking the lead but isn't that true for most operations? Even the Mozilla foundation has a Chair (Mitchell Baker) and Executive Director (Mark Surman).

Linux hasn't been a single person operation since the 90s.
