Yes, true
However, you can install your own version of Stable Diffusion and train your own models, for example on Sikhs. There is a lot of information out there about "Stable Diffusion", and basically you only need a computer with a decent / modern Nvidia GPU (which could be at your home or somewhere in the cloud).
That's a possibility, but I don't think I can do it any sooner, also it requires a good GPU for better training. But I might try surely. I do have some training experience so tools are fine.
I had a link to stable diffusion hands-on course as well, that I still need to do.
