I really think the "woman issue" is tangential at best, and distracting at worst. The simple fact is that a good deal of tech "journalism" consists of rewriting PR pieces and very little more.
Investigative tech journalism is a very rare beast, and always seems to come from major media outlets taking an interest in tech, not tech media outlets taking an interest in actually investigating something.
I would imagine this is because its rather boring to most readers. Good investigative tech journalism often just looks like Tom's hardware or anandtech. Page after page of technical specifications and comparisons to similar products.
