A computer is a general purpose device. Your Chromecast is a computer that would be capable of much more than just streaming videos if it wasn't for the artificial limitation in its software.

Now if there was a firmware switch limiting your microwave from performing its intended task to its fullest capabilities you probably would want to 'root' it too.
