It's a problem of phrasing.

Back then, for an average person, there wasn't much to do on the Internet, except online games and chatting with friends, both of which are considered a waste of time. As a result, Internet itself was demonized, and Internet addiction was considered a problem, even a mental disorder.

Nowadays, China has a booming tech sector. Everyone is using the Internet all the time to browse TikTok videos, stream TV shows, order food delivery and shop deals. And people stopped talking about Internet addiction, because suddenly they realize they themselves fit the clinical definition, which was to be online for more than a few hours a day.
