While I appreciate your concern, I suspect the risk of harm is quite small - perhaps small enough that we don't need to worry.
Providing answers to an interviewee during an interview might be harmful but it is easy for the interviewer to prevent this happening if effective use of Internet resources is not part of the intended assessment.
Reasonably, it is the responsibility of the interviewer to set the conditions of the interview, including whether access to the Internet, the manuals or any other resources is allowed. I don't know that it helps for me to make assumptions about the intended process or to try to impose my preferences for assessment on others.
There might be some people who are promoted to a position where they are responsible for interviewing and assessing others yet they are not reasonably competent to do so. There are certainly some who I don't agree with. But perhaps my limited success in life indicates that I'm not the best just judge and the relative success of some others might suggest that there are other ways than mine that are better than mine. My not answering questions related to interviews will do very little to solve such problems.
