At least here in the UK there has almost always been a distaste for 'americanisms' among the middle-aged and older (conveniently forgetting the ones that entered common use during their youth.) Its largely just snobbery and old man yells at clouds.

It is also less that the states have no culture as they only have low culture. Again, ignoring that most 'high culture' is just old, and was low when it was new. Shakespeare wrote for the common folk, Dante's Inferno was something of a hit piece on everyone he didn't like. The Rite of Spring was hammered by critics who saw it as barberous to the point of insult and suggested women should not be permitted to see it, should it continue to be performed. The Count of Monte Cristo was serialized not unlike a comic book (and was abridged to not scandalise English speaking audiences.)
