I dont disagree, but the argument I usually hear is how the only way to begin equality is to force it until people magically feel like it isnt being forced any more.
In this case however I think they're doing it mainly to damp down on criticism they've been getting. Note the link I added, as of 2018 no Best Picture winner was a box office hit for the previous 14 years. It's almost like if they make any money someone made a mistake. Those movies exist as prestige projects (EDIT and possibly something to do with taxes or subsidies).
EDIT: One thing I think is relevant is how unstable film work is. Gig-based jobs tend to attract more male applicants in general. It's not very reliable work and you always need to be on the mooch for the next project. The games industry is filled with more younger men partly for this reason. It's really, really unstable work to base a life on. Also the music industry is like this. But the real giveaway is that of lone wolf game developers: how many female ones you ever heard of? Nobody handed Toady One a job, he just stuck at it for years DIYing the whole thing. You can rattle off dozens of male examples like this, how many female ones? Literally nobody is stopping them, and is not like if they made a game people wouldn't play it just because a woman made it.
For an example of this in the film industry, 39% of media executives are women yet they only make up about 15% of total people in film production. That's because most jobs working on films actually suck and there's no job security. Sure, more men end up as screenwriters etc. But what's the actual success rate for screenwriters vs failures? The whole deal is an all or nothing thing, it's a huge gamble getting into an industry like that.
Guys are just dumb like that. Nobody is keeping women out of the grunt work on film sets, it's just a shit job that nobody but men want to do. It's like being a roadie. Most roadies are men not because of gate-keeping but because being a roadie is, objectively, a job for loser wanna-be failed rock musicians and alcoholics.
