This is not based on just fine tuning Stable Diffusion.

Where did you read that they were using Stable Diffusion?
Stable Diffusion 1.x isn't original work either; it uses OpenAI CLIP.
But training your own is pretty doable if you have the budget and enough image/text pairs. Most people don't have the budget, but at least Midjourney and Google have their own models.
Fine tuning Stable Diffusion with your own images is way easier than creating Stable Diffusion in the first place.
If you're creating your own I stand corrected and that's some serious investment.
