Associating search queries and click stream behaviour is fine if it's your own search engine. Doing it for someone else's search engine isn't (regardless of who's doing it).
In the hypothetical situation above, it has almost nothing to do with the search engine - it is both the user providing the query and selecting the result: this is the data of value, not which intermediary provided the list of results to select from.
Really? Doesn't the intermediary that narrowed the list from several billion possible matches to the best 10, including correcting the inherent spelling errors in the query carry some value?
