The problems you describe with control is severely outdated. There are tools specifically to allow you more control outside of prompts. Ipadapters, controlnets, etc… invoke and krita support layers and all sorts of other normal artistic methods for image editing. For people who use ai image gen more seriously, prompting is just the tip of the iceberg.
For the insane amount of slop generated every day though, sure, prompting is all they use.
The problem with never going there again after they reverse is that it doesn’t actually serve your goal. Companies are fickle as they chase profits, they don’t actually give a fuck about morality. Target chose to ditch DEI initially because they thought it ultimately would be more profitable. Boycotting that is fine. But when they reverse and customers don’t come back, that actually encourages them to just ditch DEI again.
