:::::The policy is the same. You will of course need to be sure that consensus supports you in rmoving material nonetheless, but that should be easy to gain if you can demonstrate that a particular source included is not about the topic of the article but has been introduced simply to contradict a tangential claim. In some cases it may have been included through a valid editorial decision that a specific source is includeable in spite of not treating the topic directly. (For example it might be relevant to include a source about the mainstream view of climate change in an article that describes the ideas of a climate change skeptic even if that source does not mention the particular skeptic that the article is about).
