Sadly this is only about chatGTP and not midjourney.
Midjourney is adopted widely by hive users and whales r seeing it as grey area.
On personal level I dropped my curations from original to 50% lower upvote if I see midjourney. This is my step 1 to stop AI images from spreading. The technology looks good but it is doing damage to artist. Also, diffusing models takes data without permission from artists for training.
