Who defines what "good" or "positive energy"? Who defines what is fake news? Does providing users information that is "not tailored to their personal characteristics" mean that it's, instead, tailored to the state's preferences?
The language of the law sounds nice and there are aspects that probably meet goals that are not necessarily harmful to people (e.g. Addicted people are less productive, so avoiding addiction is good for the state as well as the individual), but it definitely could be used by a state to control what people see online. That's political control of media.
If you wouldn't be concerned if this passed under Biden, how about if it were passed under Trump? Remember what he called "fake news"? How much more should we be concerned about it being passed in China, where state control over media is absolute?
e.g. Anything involving the Tienanmen square massacre is virtually guaranteed to be classified as "fake news", "not good", or "not conducive of positive energy" by this law. How do companies like facebook ensure they're compliant with the law then? Censorship.
This isn't good news. This is absolutely dystopian.
