I wouldn't expect everyone to know or to remember what Toshiba did. Selling the tech needed to improve the Russian Nuclear Subs propellers only made it into the papers for about a day or two and as far as i know it was barely mentioned at all on TV.
It all happened back in 1986 or 1987 - Toshiba sold milling machine technology used to mill our sub props as a single piece.
I was in college at ISU at the time, owned a Toshiba boom box which was thrown out of my car window at 55 miles per hour after
a few many beers after leaving the local races.
The labs for one of the electronics engineering programs I attended used Toshiba oscilloscopes and one of the teachers had ALL of them removed, returned to Toshiba and replaced with Hewlett-Packard units.
Oh and the teacher - Vietnam vet and joined us for many beers at the local pubs.
