Because it is a virtual object. Don't forget, national laws currently manage entities rather than virtual objects.
Just like you can steal other people's equipment in Shanda, if you steal other people's computers in reality, the nature is different!
Even if, as you said, it is actually a disguised cash sale, the goods or prizes obtained are virtual. Different from the actual definition of cash and actual goods in judicial interpretation!
In this field, China's judiciary has not kept up, resulting in many loopholes!
You saw it! What you said about "general knowledge about strengthening lottery market management" is just a general rule, not a law. Therefore, the maneuverability and variability inside are also very large. There is also a lot of room for judicial interpretation.
If you look for it in the provisions of civil law, it is estimated that there is not so much room for manoeuvre! But it is only a normative document after all. Not a legal document!
So! A more accurate definition should be: it may involve violating the law, but whether it violates the law may only be the most authoritative judicial interpretation made by the Supreme People's Court. Other statements are just guesses or speculations!
