So, Windows 10 actually does not complete against Linux or PC-BSD, it completes against previous versions of Windows without telemetry crap, i.e. Windows 7 and Vista. Exactly these operating systems with disabled updates will dominate for the next 20 years, not Linux or BSD.
Btw, this approach (disabling updates) also solves all well known problems with long time reboots, metered internet connections, tray nags about Windows 10, insufficient disk space to save old OS etc.
