Companies have "woke" consultants in to make speeches all the time but it's performative and it never changes anything.
After that the environment became so toxic that many people left anyways, and some clients went after this employees.
But if you consider that roughly 86% of the studio at that time was male, it would have been easy for something to slip through that could have been perceived as anti-women.
A great example is in the game Hitman; there is a moment where you're infiltrating a strip club and an option exists (although, is penalised) for murdering a scantily clad stripper. This was caught by Sarkeesian and used as an example of poor game development that allows for the objectification of women. (or, women as background objects)[0]
We didn't want that.
I would guess that genuine efforts are few and far between.
