Again it’s not a guarantee for entry.

You can argue however you want, and I really feel for those whose 10 year visas were cancelled. And I do think the Chinese government should consider revalidating the visas. But visa by definition is not a guarantee for entry and can be cancelled.
The purpose of a visa is to allow you to travel to a port of entry, where you present yourself to immigration and border control. It’s not a guarantee for entry. At the port of entry the immigration officer will determine whether you are admissible.
