Through the 1960's, the majority of computer science jobs were held by women[1].
Your worldview is not compatible with reality.
This.
You can even trace when it happened by clustering the awards given to Margaret Hamilton:

The problem is that today the supposed CS skills are atrocious. Most self called "engineers" would be laughed at the rest of the world. And, if they dared to stay in an actual engineering job in Europe (with civil accountability) without a proper degree, they would end in jail if something really bad happened. Literally.
In the open source world big tech are trying to use the diversity as a way to cynically get representation for themselves. They hire people who hit their diversity quotas and then use them for open source outreach to get their voices amplified among the progressive minded who actually... write all that open source.
The people who would be pushed as candidates for open source boards (e.g. black people doing dev outreach for Microsoft/Google) are blameless (they need a job!) but they are still being used by rich white men to serve a mostly corporate agenda.
This isnt to say that we dont need more diversity, just that we should recognize when the shallow appearance of diversity is being cynically used as a corporate and political weapon by elites to push a regressive agenda.
This strategy is very similar to the one employed by one of the most racist countries on earth, although theyre more blatant and less implicit about their accusations. The strategy works very well, too - progressive minded people can be easily manipulated through guilt.
