For the same reason it makes sense for everyone to collectively to pay for public schools, including those who do not have kids.

In places where population growth is not a concern, such as in the U.S. where birth and deaths are at equilibrium, those who have and raise children and do it at least reasonably well are producing positive externalities[1]. And the better the children are raised and educated, the more the positive[2]. Policies like Netflix's thus benefit society as a whole.

[2] The flip side is that when children are raised poorly, be it the fault of the parent or the society that sets the parent up for failure, it turns negative.

A country like the US would be better served by immigration than having its own children. You could choose only the best of the best in the world to grow your population instead of throwing the genetic dice.

But that's beside the point; we don't have Netflix pay for public schools, the state does that. Similarly Netflix paying for maternity/paternity leave seems silly to me.
