No, it is about both. If you don't have anything you want to do then everything with any fun elements at all become "addictive". Removing those "addictive" activities from such a person wont help them at all, it just makes their life more boring and they will take it up as soon as you give it back since they have nothing else to do.

Some people have problems with addictive activities. But lots of people just do it since they lack alternatives. If you try to fix the second as if they were addicted then it will all feel frustrating and hopeless since you aren't addressing a real problem.
