> Internet addiction, also known as “compulsive Internet use,’ ‘problematic Internet use,’ and ‘pathological Internet use’ (Zhao et al., 2022), is not officially recognized as a mental disorder by the American Psychiatric Association (APA; Kuss & Lopez-Fernandez, 2016). However, Internet gaming, a subcategory of Internet addiction, is formally included in the 11th version of the International Classification of Diseases (ICD-11) by WHO in 2018 (Poznyak, 2018). Internet addiction is defined as the excessive or uncontrollable use of the Internet leading to symptoms of withdrawal and tolerance (Young, 1998). Although there are no official diagnostic criteria for Internet addiction, Young (1998) based the diagnostic criteria for Internet addiction (IA) on the extreme gambling criteria as suggested in DSM-IV. The four characteristics of addictive behaviours: excessive use, withdrawal, tolerance, and adverse psychological consequences are often found present in Internet-addicted individuals (Fumero et al., 2018).

That's a problem, because the extreme gambling criteria is irrelevant to "internet addiction"...which is not a recognized disorder. They are making it one by using the criteria that fits their need for internet addiction to exist.
