Somehow "Have millennials killed X?" turned out to be a really good clickbait article format. I suspect that this is due to clickbait becoming widespread as millennials came of age. At this point it's just going on momentum.
Don't forget ageism. Older people love memes with "back in my day" in the headline that shows some perceived difference between when they were young and the youth of today. I have friends who sometimes share that stuff on their social media. When I jokingly called out a friend recently about his "back in my day" jokes, he didn't even realize he was indulging in ageism. I imagine most don't.
