If you really look hard at what we call British, then investigate actual ownership without even getting into the complex world of shareholders, etc, you won’t exoect to actual find much that is anymore.
Then what happens when something was British, was in foreign ownership for a while, but then moved back into British ownership? Are they expected to rebrand every single time?
I kind of follow your way of thinking, and that’s cool, but I don’t agree to the same level. My opinion it would be wrong if a company was created in Sweden but branded as if it was Italian but never actually had anything to do with Italy. I don’t agree that a company, that was founded in Italy in 1885 but was sold to a Swedish company in 1996, should be forced to rebrand as if it was Swedish all along. That’s just obvious to me.
