No, it has not. What on Earth could possibly be wrong with a young person reading our discussions here on Lemmy and expanding their knowledge about all the topics we discuss here, for example? Even participating in it, asking and answering questions about any topic they find interesting? I find it hard to think of a more harmless hobby.

I myself started regularly participating in online communities at the age of 10 (that was more than 20 years ago, when there were not yet even rumors of a product called "iPhone" and I didn't even have my first own desktop computer yet). The vast majority of my joyful memories of my preteen and teen years stem from my participation in online communities. The vast majority of memories I have of pretty much anything else during that time period are negative. Online communities taught me many important things about life that I now use every day and that I probably wouldn't have easily learned elsewhere. They turned me into a more creative person with better communication skills, especially in writing.

So, no, the situation is not that people who want to ban young people from social media have a noble goal that oh-so-unfortunately cannot be achieved without invading everyone's privacy. The situation is that those people have a completely illegitimate (in my mind, outright evil) goal in the first place.
