There is pretty much no way this was ever not going to happen, given Wikipedia's position and structure. It is a massive repository of knowledge, that is consulted by millions if not billions of people around the world on a regular basis, that is (in theory) editable by anyone and that has articles on just about every conceivable topic, including many politically charged ones. There must be immense pressure to use it to propagate all kinds of narratives. Given all of that, I think it does as good a job as can be expected of remaining objective, but absolutely you need to be careful when reading articles on politically charged topics (which is true of all media).
