I think the position being expressed here is more that in the real world Google is now part of many work flows and so a test that asks you to be cutoff from it is actually unrealistic. I don't fully agree though because a test is also unrealistic in that it often gives you more than enough time to solve the problem. And maybe more along the lines of what you're saying because again it's a test it can't really include truly novel problems that won't have known solutions
