You're confusing the people who wrote the code with the product (business) team that decided they could monetize it. Engineers in large companies have zero creative control, and the people who do look more like wall street finance bros than the guys on silicon valley. Not that they don't also suck, but please get why they suck.
Tech bros refers to a misogynistic behavior within tech circles and especially software development tied to traditional ideas that women can't be technical because their vaginas get in the way. As a secondary bonus this leads to women trying to crush other women.
