It's interesting that they went to the trouble of retrospectively changing things, though. It got me to wondering how many people these days say "caff" rather than "café"? Fewer than of yore, I'll warrant. That was always partly a class thing, of course, with the question of whether something was a caff or a café depending not only on the speaker but the establishment in question. "Greasy spoon café" wouldn't sound right at all, to my ear.
Then there's Michelin - perhaps an even more interesting case, since the same company is well known for three different things, each of which falls into a different stereotypical class bracket...
Meesh-e-lain (last syllable to rhyme with the French word for 'bread')
More than one of the above, depending whether it's in connection with tyres, travel guides or restauruants
More than one of the above at different periods of my life
Some other answer, which I will explain in the comments.
