Ask me how I know you didn't read the article. It touches on that, but mostly talks about how women were seen as convenient because they were cheap. The conventional wisdom was also that women would leave when they got married or had kids, but as computers got more powerful; the old boys club decided they needed to own those jobs too.

I read the article and still don't understand how women are really prevented from working in IT in the present day unless its mostly because many don't desire to.

Like hires like. It's incredibly difficult to be the odd one out.

The narrative that a boys club consciously conspired to take any jobs is quite a silly one.

Conscious or unconscious is really irrelevant.

There was a time that nobody would have considered education peasants. It was not a conscious bias.

Times have changed and will continue to do so, we need to do what we can to correct the mistakes of the past.

It’s quite relevant. The point is nobody pushed anyone out.

Independent autonomous people making decisions about which field they would like to study and seek employment in is not a mistake that needs correcting.

Your ignoring history. The ones making the decisions pushed them out. The ones doing the hiring, not the women deciding what to do.
