Apple's just doing what's on the agenda, plugging the analog hole. Your TV doesn't have a headphone jack any more either. TVs haven't had this in decades.
My TV does have an audio jack. It's a cheap dumb TV. And almost all of my electronic devices have a 3.5 mm jack.
You won't find it in top flagship models, but plenty of budget devices still have it.
My LG OLED TV does have a headphone jack, and I send that through a mixer (combined with my CRT gaming setup's output, my record player, and my PC's output) to my stereo.
