Some things are objectively addictive. For instance, alcohol is an objectively addictive drug. If you don't have trouble controlling drinking now, that's excellent, but if someone were to somehow force you to drink 6 drinks a day for a year you would certainly start to develop physiological signs of addiction. On day 366 when you were free to not drink, you would feel a craving. There is no such thing as a person who cannot become addicted to it. It is the drug which is addictive, and not some failing/property of the person who became addicted.

In particular with social media, I don't like the framing of it as "what is addictive to someone is harmless for someone other". The addictive-ness is baked into the product whether or not an addiction is manifest in any individual user. Viewing the addictive-ness of say, Facebook, as a problem only "for some people" rather than as a property of Facebook, shifts blame away from the engineers and execs who purposefully make their product addictive, onto users who find themselves (somewhat innocently) addicted to an the addictive thing.

Don't want to be pedantic but I think it's an important point.
