I have no issue with the youth coming up with new slang or changing the definitions of words that are no longer as relevant as they once were. As you say, language evolves like that. But when the changes to language are being top-down forced by megacorps so they can more effectively target ads to children, that's when I want them burned in fire. I'm honestly surprised at just how justified I feel in being mean to the people who propagate this bullshit.
