I remember a time around 2010 where I benefitted from social media, Facebook in particular. It wasn't addictive, I used it for 15 minutes at the end of the day to catch up with what foreign family was doing, we would organize real-life parties through Facebook, share photos of those events, tag each other. If you traveled internationally it was easy to keep in touch with people you met along the way.

I'm afraid we will never get to that point anymore but I do think there was a point in society where social media was a positive addition.

It could still be like that if there was no opaque algorithm and even better if there was no endless feed to doomscroll. If you only got alerts for messages directed at you and otherwise had to actively visit a person's page to check up on them. But that wouldn't be as engaging (ie addictive) and there wouldn't be nearly as many opportunities for ads or even the collection of data to drive those ads.
