Buyers may not know or care, but retailers do. Anyone can report that Amazon link shared earlier and Amazon will remove it as it is not spec compliant. Those type adapters are also non-existent at basically every electronics brick-and-mortar store I've visited.
Amazon has had this policy for years but unfortunately enforcement is a complete joke and they remain full of noncompliant hardware.
I do find it interesting that they ban noncompliant Type C devices but not noncompliant Type A devices. Probably because the Type A current spec has got to be among the world's most-violated standards.
