An important aspect of this situation is that it is evident Asus customer support have on many occasions legally enforced the beta bios disclaimer as warranty void and the people affected by that dumb decision get stonewalled into reluctantly accepting it as a matter of fact.
Evidently Asus customer support lied to these customers, and here in the UK, it's a criminal offence to lie on behalf of a company. I don't think Asus staff should be prosecuted, it's more of a dumb overreach that has become the industry norm, and the responsible people higher up also have the dumb duty to not have a moral compass meaning they turn a blind eye until of course they have no other choice.
