I feel ya. I used to read a lot of manga and watch a lot of anime back in the day where there was a lot more diversity of material. Unfortunately the collapse of the industry in the wake of the Japanese bubble bursting gave them a lot less leeway for artistic creativity. What survived created the moe boom of the 00s, and that fed into what we now see. Basically pedophiles were willing to pay to read/watch what tickled their perversion, and so that overtook the industry.

It would be like if US media collapsed, but furries were still willing to pay for what got them off. In a decade you would see most US media catering to them.

There is still good stuff out there, you just need to either wade through the shit yourself, or get guided by someone that bit the bullet and did it for you.
