It's worse than that, the algorithms these companies use sometimes purposefully promote these random claims because they lead to more user engagement. For example teenage girls searching for weight loss on YouTube were more engaged when shown videos on eating disorders like anorexia. YouTube addressed that by tweaking the algorithm, but there's an endless number of edge cases like that and fixing it by tweaking the algorithm is like playing an never ending game of whack-a-mole. It's fundamentally unwinnable - the problem is optimizing for engagement itself. As many people here may have noticed at some point, the same thing happened with flat Earthers and other conspiracy theories. In fact for a while it was common knowledge that you could start on any YouTube video and keep watching from the recommendations, and with an hour or so that would eventually lead to crazytown - videos just showing bigfoot and aliens and flat earth stuff.
