Maybe an unethical Wi-Fi manufacturer thought they were clever to deauth clients of APs with MACs not in their own range, to clear other traffic off the band they use and have their products perform better than others by means of sabotage.
That surely would be noticed in any sort of rigorous certification program.
What 'rigorous certification program'? Aren't the only regulations that they comply with FCC rules about creating/accepting interference, frequency ranges, and transmission power? These regulations do not have any say on what is actually transmitted on those frequencies.
