There's sexism in tech, and to address it you have to call it for what it is. I'm glad her experiences are such that she hasn't encountered these barriers, but other people have, and they need these words and spaces.
Take my previous job. Women were objectified on Slack. A woman was groped, though she didn't report it out of concern for the repercussions. In meetings execs, male execs would only address/look at the men, not the women. The company was 91% men, even though 24% of the workforce for those jobs in the area was female.
My friends in another high-profile company in the area were sexually harassed, though they felt like they couldn't report it. They simply left the job.
I've mentored young women in high school interested in STEM in a program specific for them. The content is the same, but there's value in having these to counter the obstacles specific to women that they'll face.
I've never seen men, as a group, encounter the obstacles I've seen many female peers discuss. Not all women encounter these, but as a group, it's undeniable that there's extra obstacles.
