While most pieces of writing about getting more women in tech seem to propose the problem as "How to Add Women to Tech", the real issue they're addressing is "How to Remove the Unnoticed Barriers to Women in Tech".

Like any other majority, the male majority of the tech industry often take for granted a number of things as "normal", "everyone does them".

People should absolutely "just hire the people who can do the work", but they should assure that their company and process are not set up in a way that, unbeknownst to them, turns off a certain minority whose needs they fail to recognize. These posts are trying to highlight those needs or differences so that it's easier to break that "normal" barrier.
