It's not. It's supposed to target certain open source AIs (Stable Diffusion specifically).
Latent diffusion models work on compressed images. That takes less resources. The compression is handled by a type of AI called VAE. For this attack to work, you must have access to the specific VAE that you are targeting.
The image is subtly altered so that the compressed image looks completely different from the original. You can only do that if you know what the compression AI does. Stable Diffusion is a necessary part of the Glaze software. It is ineffective against any closed source image generators that have trained their own VAE (or equivalent).
This kind of attack is notoriously fickle and thwarted by even small changes. It's probably not even very effective against the intended target.
If you're all about intellectual property, it kinda makes sense that freely shared AI is your main enemy.
