That may be true, but the spectator is the one doing the talking, so he gets the infraction OA if its deemed strategic relevant to the judge (which it is for me, and what the consensus seems to be here).
The opponent didn't engage in the conversation, and asked it to stop. Yes, he might have done so earlier, but he certainly hasn't solicited the advice, and I'd not give him the OA penalty.
Whether the player that started talking should recieve the OA penalty: He might. The IPG is a bit fuzzy on this. The definition of the penalty says:
“Seeks play advice or hidden information about his or her match from others”
While in the philosophy it says: “Any strategy advice, play advice, or construction advice from an external source is considered outside assistance.”
Usually, the spectator gets the OA warning when they uttered some strategic information, but it's often a lot harder to see whether the player actually sought out advice. Since the player started talking to his friend about the current game of Magic, it can be argued it's seeking advice. He certainly expected his friend to answer.
Reading this line from the philosophy section, we should ML both players, since they both recieved and could benefit from the information from the spectator. That clearly is not the intended outcome.
Note that in practice, it's relatively easy to get confirmation that the spectator actually gave advice (mentioning a card name relevant to play around is clearly enough), while it's harder to determine whether advice was asked for. These questions on reliability of evidence are relevant to the decision on the floor, but we can disregard that here on the forum, where the OP states as fact what was said.
Regarding cheating - you should always be on the lookout for cheating. P asking for advice knowing it's illegal. O waiting to call a judge, so his opponent gets a ML for sure. Spectator already out of contention taking the chances on a DQ to help out his friend. However, in reality, most of these OA things are because people blurt out something without thinking, don't know the penalty Outside Assistance exists, or simply don't care, because they'll win the game anyway with the card they're searching.
