Looking from another angle from Yoko Taro's point, I'd say that, in fear of failing due to being too big, companies would rather play it safe, but that causes creations to grow sterile.

And as consequence, people allegedly "weird", which I wouldn't think are necessarily people with curious antiques as Yoko Taro himself, but simply people whose game ideas are far from a safe ground, go for making indie titles instead as then they can be free to do whatever they want.
