Even with nostr design, there obviously are ways to make this work with a great UX, I just don't think there is an incentive for people to work on it.
Though kinda strange considering that most of the things people consume on social medias is video.

I don't think it's a matter of incentive, world is just too sick to quit addictions to corporatism and stuff
It's not lke the corporations walk to your door and shoot you up with heorin and you are addicted.
At the end of the day you are very free to stop, in fact I think taking personal responsability for one's social media addiction, it the only way to avoid it.
