Use of the word "buss" to refer to electrical or mechanical power distribution predates the Bussmann company by a good 30 years or more (it's used in engineering documents and handbooks from the 1880s). It probably derives from the Germanic / northern European / Scots gaelic of the time, since they were big engineering regions.
But don't let that stop your misplaced outrage. Why not turn it to the common mispronunciation of "router" (i.e." rowt-er") instead? "Rout" (pronounced "rowt") means " to turn aside; a disorderly retreat or decisive defeat", while "route" (pronounced "root") means "a way or course taken in getting from a starting point to a destination". Which does your router do?
Hence, the device used in networking should be pronounced "root-er"...
(Notwithstanding the fact that most of them should be pronounced "gateway", since that's the correct networking term for a device that interfaces between different physical transports or protocols...)
