I don't understand what you think the author is doing if it isn't trying to send men on a guilt trip as the first part of a process of self-improvement.

She explicitly admits as much: "Are you feeling angry, defensive, or threatened? [...] It can be especially painful when someone gives us feedback that sounds like, in essence, that our best isn’t good enough. [...] I’ve learned that these feelings [in myself] can indicate that I’m on the right track."

The title itself says, "Men, we need you to do better." Ergo, men are failing. Maybe they are, but this isn't what you write unless you want to draw attention to the failure in an emotionally negative (e.g. guilt-inducing) way. "Men, here's how you can help women everywhere!" is the kind of thing you say if you want a positive outlook.

You write "no-one's asking you to feel guilty". She writes "it requires us to face our own shadows and confront ourselves as we are, shortcomings and all. To make amends where we can".

We have shadows, shortcomings, need to confront ourselves, and make amends...but none of this should make us feel guilty? That seems highly unrealistic.

I really don't think you've taken the measure of this article.
