I recall hearing as a child that the Quetzalcoatlus wingspan was estimated to be 50 ft. at least. However, in recent years the tide has turned in the scientific community, with many prominent paleontologists claiming it to be 33 ft. or even less. It seems like a narrative is being pushed in which the importance of the previously undisputed "king of the winged lizards" is being diminished in favor of lesser known pterosaurs like Arambourgania or Hatzegopteryx, but for what reason?

I tried editing the article for Quetzalcoatlus on swedish Wikipedia regarding wingspan (nothing too controversial, just that it had been disputed over the years) and it was deltid within 30 minutes with threats of my IP being banned for spreading misinformation. Obviously money is changing hands somewhere (research gants, etc.) and pro-Quetzalcoatlus sources are being censored. What's the endgoal?
