It did. Onboarding people onto embedded programmer.

You just ran it, wrote few lines and you had working blinky. Write some more and you have useful toy. You could even technically make products with it but going from this to C++ was easier coz you already know what you could do, just needed to go thru pain of switching the toolchain once you're already invested.

Compare that to "you need to setup compiler, toolchain, SDK, figure out how to program the resulting binary, map the registers to your devboard pins etc."
