This is the line that is often repeated but it is simply not convincing except to people who are on that side (which is my side too if that matters). To me, it is obvious that a number of opinionated decisions are made in writing a Wikipedia article, and those decisions are consistently biased. In the last 10 years or so it has been REALLY bad and if you consume information from many different news sources, it is easy to spot the bias Wikipedia carries despite it trying to look like a factual and neutral source.
Every assertion I checked from that article is false. So there is no evidence Wikipedia has a bias.
Meta makes far more money from scammers than they will from you so it's in their best interest.
