Especially as ARM originated from Acorn, whose success came from manufacturing the BBC Micro, for a publicly funded organisation (the BBC).
Acorn were also almost overlooked in favour of a company called Grundy, which had government backing, but inferior technology.
I did quite a bit of real paying work on BBC Micros back in the day, and think they were great - but reading the way people tell the story today, one would be given the impression that the NewBrain was some kind of grim socialist piece of junk. It was actually a pretty decent bit of kit, quite a bit better quality than many of the other micros on the UK market at the time.
In an ironic turn, the company I worked for doing the BBC stuff later moved into Grundy's old premises in Teddington after they went bust.
