Junk food addiction (your word, not TFA’s) is also not in the DSM V, so appealing to authority like that or hanging on the word addiction gets you nowhere as far as whether the comparison to social media is interesting. For what it’s worth gambling addiction is in the DSM-V. What’s it’s direct route to biochemically alter the brain, like nicotine and food intake?
Gambling addiction is not in the DSM-V, it's gambling disorder, and it's grandfathered in as the only behavioral disorder of it's kind.
