I don't fully agree that that is the reasoning. Addictive algorithms or not, Facebook/TikTok et al can and does track you comfortably (as do most states including China).

But if you observe some recent laws you'll see that the government sometimes does do things that are (what it thinks) is good for its citizens. For example there was a recent law limiting gaming hours for children. Agree or disagree with the implementation, a state can simultaneously be doing terrible things while also trying to do good things. Governments are not a monolithic unit.
