Maybe it is for a "beta" male audience, but it can also be for the many fathers who don't have the fortune of having a present partner or an excellent relationship with their kids.
Also, I don't agree that "any content is useful". Men and women are different, and maybe I will get roasted for this, but it's true. The life experience and sensibilities of men and women can be very different, and only having access to a mother's perspective (which also happens to be the mainstream-approved perspective) is inadvertently gaslighting; if a father naturally has certain male perspectives on raising a family but the mommy blogs they read tell them otherwise, that's very alienating.
