The article is not asserting a problem with the quality of the results - what they are asserting is that it is a problem when I (as party A) as Google (as party B) a question, and google gives me an answer, rather than always going to parties C, D, E and F for the answer. Personally, I am torn about this one.
On the one hand, I feel that if party A asks party B a question, it is not the right of parties C, D, E and F to be included in the process - Since the answer is trivial and party B is giving party A what they asked for - If they were better at giving party A what they require, then party A would simply ask them instead.
On the other, I am disturbed at how much potential power this gives party B, no matter how benign they appear to be.
