Growing up, portable cassette players were always called "freestyles" here. I never knew it was a marketing thing, or that some other countries also objected to the naming.

This is fake news! It was always called "Tragbares Musikkassettenabspielgerät" in Germany.
the swedish language council tried to make it "bärspelare" as well, but to no avail
