Short version: it's a lot easier to complain ..er...critique than to create.
Long version: You aren't the only one questioning a lack of creative drive. As unsettling as it is, I have more respect for someone making nude mods of something like Skyrim than in all the feminist critique I've seen. Modders built. They learned the skills they needed to do so and created things they wanted. Even without personal skill, kickstarter exists for a reason, and for the right price, any indy developer would at least be willing to hear you out.
Yet when it comes to feminism issues, the idea of actually taking action yourself seems foreign. I could entertain conspiracy theories about how it all isn't about getting something they want, but in getting others to quit making what they don't, or act like an old curmudgeon and complain about how kids today only ever learned about getting things by whining until mommy and daddy bought them the toy they wanted, and while I'm sure there is some truth to those, I think it's largely something else.
Being an online critic is easy. Get a blog and write. Get a youtube channel and talk. Post of forums. All pretty much involve little more than venting your spleen at what's pissing you off without any form of editorial oversight. Best of all, if you get a following, you can pretty much make it your day job. So given that, which would you rather do: try and make a go of it telling others how they're screwing up, or put yourself out there to have those same critics rake you over the coals. Factoring in the effort to learn new skills, and both the initial cash outlay and long term financial risks involved, there's no surprise people would rather just sit at their computers and wag their fingers at others.
This isn't to malign critics or devalue decent criticism, just to point out most people would rather strive to be the next Yahtzee or Jim Stirling than the next David Cage or Shigieru Miyamoto. Some might even think that this is their way in like how it worked for Gail Simonne or the guy that created Wonder Woman. Still, I find more to respect in a doer than in that doesn't have skin in the game.
