Technically correct. We can't call every compulsive behaviour "addiction". Using a social app for 16 hours a day is a very serious problem and requires treatment. But it's not addiction in the same sense that other commonly-recognised addictions to substance and even behaviours are.

I'd call every enjoyment that isn't practiced as a ritual an addiction, and healthy rituals should not take up more than a fraction of the available time.

With 16 hours of daily use (and 8 hours of sleep per day) I wouldn't contrast the batched consumption here on an hours/day-basis, but on a days/year-basis, like going on a trip, a festival etc. Since that basically results in all the days available each year here, it isn't really a practiced ritual anymore, but a complete lifestyle.
