t's for people that enjoy tinkering with computers rather than getting work done
I do like tinkering, but one of the advantages of using Limux/BSD is the lack of annoying disturbances while working.
No nagging about Windows updates or forced reboot, no nagging about the virus scanner doing anything, no nagging of programs needing updates (Adobe, Java, etc.), no nagging advertising (apparently), no nagging about no internet connection if the router or firewall reboots, etc.
My barebones desktop environment (by default totally blank with a clock in the bottom corner) provides me the setting to do what I want to do on the PC; use the programs I started without any distraction.
