It's in general very negative; it's only "positive feedback" in the ultra-narrow technical sense wrt reinforcing the compulsive behavior, which is negative to the user, negative to the user's wellbeing, friends, family, negative to society.
My analogy to reinforcing any other compulsive damaging behavior stands. It's not "positive feedback" to the dealer or casino.
Let us not let our words do the thinking for us, as Orwell cautioned.
