I think a more analogous question would be: - Is there such a thing as food addiction? Food is certainly something with a lot of utility, which we need to survive, and there is a lot of healthy food out there. But we're also able to create hyper-palatable foods - like cakes and fast-food hamburgers - which effectively hack the brain's reward system: i.e. the reward signal you get from eating these foods is greatly outsized compared to their actual utility. Some people are able to enjoy these foods in moderation, and other people cannot resist the temptation and eat these to the point that it's detrimental to their health. I think it can be argued that the internet is a lot like that.
