You will come across people like this- generally, they're people who have had very strict rules about usage drummed into them in private schools and through class systems- like the people who get excited about people saying ketchup. You normally find them introducing a useful phrase that is coming into BrE as an ugly Americanism- a decade or so ago, they were prefacing dumbing down with a similar label.
You missed the key quote:
Old buffers like me have always complained about the process, and we have always been defeated.
It shows their influence and impact. There were complants in the 1960s about the Beatles- they should have sung She loves you, yes, yes, yes to avoid ugly Americanisms. All countries have their fringes.
