This seems like an uncharitable take. I can't imagine how an alarmist approach is "100% valid" when there are not any known problems caused by this. The article is only stating that living in urban environments is correlated with a decrease (by A Lot) in gut microbes. Even if it is true that a significant decrease in gut microbes is a Bad Thing, the article does not argue that well. Indeed, it seems to intend to argue that with little or no substance.

If the comments are just criticisms about the content in the article then they seem apt. Many of the points hold up when I am critical about the article's arguments. It's possible to argue that position and also be in favor of publishing this information.
