Implicit in your statement is the proposition that quitters are a self-selected group of people with a disordered consumption pattern - a moderate social drinker is not going to quit.
But I do recall an instance where everyone in some college class or something were supposed to abstain from social media for a week, whether they had a healthy relationship with it or not and the group reported substantial increases in life satisfaction.
Without a reference, this comment doesn’t indicate anything.
If I asked you to abstain from any behavior for a week to see if it would improve your life... I bet most studies would show abstention helped.
The relevant question is how this intervention helped, compared to other interventions that could be seen as similar. Eg, if you didn’t watch tv for a week, how would you feel?
