It is backseat gaming though, and OP is (from what they said, I don't know the tone of the voice at all, but by the words to judge) completely overblowing the streamer's reaction. If the streamer basically told them to F off, I would have been more implied to not defend the streamer in question here, but really from what the OP says, this is a normal reaction to an all too common problem on twitch, people who wants to be helpful when the rules even says they don't want help.
