It's not like Airpods are the first wireless device that go in your ear? We saw the same thing with bluetooth headsets in the early 2000's, and the joke/meme that became. Like that, it's just a fad that will fade over time. This is no different than being rude with any other type of headphones in your ear while talking with someone. It's not like Airpods invented someone being a rude jerk. If someone has Airpods in during a conversation, and it bothers you, be an adult and politely ask them to remove them, just like you would if they had ear muffs on and you weren't sure if they were listening. It's not that big of a deal.
Carry on, and worry about much larger problems in life than silly nonsense like this pretending to be "news."
