It's not fine at all? Before social media the average was 28 hours a week of viewing per person, obviously a non negligible percent of people watch TV for 100% of their free time.

Modern social media is even more addictive - always with you even when you're not home, short form, customized to your tastes, you can skip videos so you no longer need to feel any pain at all.

TV is not 100% curated for your personal tastes based on your previous interactions.

It was fine for years because it was a generic service in which everybody was forced to view the same content in the same way.

They are very very different things.
