More basically, men simply won't know or the importance won't cross their mind, even if they do kind of know.
I do my best to leave informative comments on HN with details men are unlikely to know, such as this comment:

I will add that the high cost of feminine hygiene products is a problem for a lot of poor American women. It isn't covered by Food Stamps. Homeless services have limited quantities of such things. Etc.
That being said, I'm on the fence about believing this is more than a question of habit vs an actual thing that will bug you. After all, the average US woman seems to be completely thrown about how you can use a tampon without an applicator. In Europe if you ask for them, most people won't even know what you mean and I don't see what their appeal is, but if that is what you grew up with....
(edit) Just to clarify, I also use a cup and it has upsides and downsides, but overall to me it is a net win.

Here’s one: since men are larger and headboard than women, we need more food just to stay alive! A few hundred extra calories a day over a lifetime, the cost must be substantial — almost certainly greater than the cost of tampons.
Life is unfair to all of us, both sexes.
Men also get pressured in other ways, but very rarely are they directly monetary/consumptive the way women are in my opinion.
You as a man can choose not to east as much as you need. You grow a bit less and need less food. A woman can't choose not to leave the house 5 days per month if she want's to keep a job. Yes, we can keep arguing over this but I though we were done with this already 50 years ago. I'm a bit surpriced to see it to be honest. We talked about this in school when I was 12, 30+ years ago.

Last year one county here started with free menstruation protection for 12-23 year olds [0] (swedish...) Apparently Scotland was first in the world 2017 [1]

Now if there's a way to make money, suddenly it becomes an attractive subject for some, but the liberation of women with reusable products (menstrual cup, washable pads and period pants) will always come second to potential wealth increase with single-use solutions, especially for someone who does now experience the "problem" in the first place.
Worse than all that, the people in charge of pushing single-use products genuinely believe they are helping out women, when in reality we see cases of toxic shock syndrome due to chemicals in tampons, and the ecological impact of such single-use products.
My wife has been using reusable solutions for a few years now, the cup and period pants being the most liberating according to her.
