Except that Genshin will not be subject to it. Genshin Impact is made by Mihoyo, a Chinese company. In order to sell Unity licenses to Chinese customers, Unity Technologies created a joint venture called Unity China, and, as is standard Chinese government policy, it must be majority-owned and controlled by Chinese entities. The majority owner of Unity China? Mihoyo.

(On top of that, it makes no sense — Genshin would be a poster child for revshare: a single entity that has made billions off microtransactions and that can be easily audited in one go.)
