In the UK, Quorn is as ubiquitous as soy. I eat it regularly, and I have a fairly average diet - I eat pretty much anything. Stick a chicken kiev on a plate next to a Quorn kiev, and you really won't tell them apart.

I don't remember there being such a hoo-ha in this country about it. We just accepted it as 'being like mushrooms' and chose to take it or leave it.
