There's one famous US magazine that set up a UK branch. They hired an editor who said in his two-sentence biography that he's "a descriptivist, not a prescriptivist". As a result, this editor didn't edit. And given that he was writing to an audience of nerds, most of the responses to his articles were people taking issue with sentences like "Thanks to the improvements in AI that have happened due to Moore's Law..."

Needless to say, the UK branch got closed down.

Your analogy with funeral attire and Hawaiian shirts is excellent.
