This pretty similar to why I stopped watching their vids. I always thought they were a trusted authority, until they covered a product that I had some familiarity with. I wasn't even an expert at it, I was just interested so I read some articles, visited some forums and subreddits about it for a week or two. Their video on it had a couple of mistakes and they omitted a couple of minor features, but were important to me. There was nothing egregious but it was pretty surprising to me that in this one thing, I knew more than them, despite not doing much research.
