Ever since it came out I've asking myself why is it called "Windows subsystem for Linux"?! Isn't Linux that's actually running as a SUBsystem, since Windows is the host?!
Some stupid rules (probably around patents) prevent them for starting the name of the project with the word Linux. Since they own the Windows brand, they can start the name of the project with that.
Yeah, this drives me nuts. Even if they can't use Linux at the start of the project name for copyright rules or whatever there must be another name that isn't the exact opposite of what it is.
