No, I think it's a completely fair assessment. In fact, it probably doesn't even go far enough in terms of criticism. These two expats are notorious in the non-expat world for perpetuating unsubstantiated stereotypes and myths about China for the sake of views. They know there's an audience for it and they've adjusted their content accordingly. Somehow, they've managed to convince a vast number of people that they are experts on the subject matter despite all evidence to the contrary. If you listen to what they say you'll end up with a very distorted view of reality.

As the parent commenter said, there are plenty of higher quality Youtubers and vloggers who do a much better job at describing what life is really like for expats living in China. In general, the more reliable and accurate sources are the people who don't make their living from producing clickbait videos.
