For example, I know artists who are vehemently against DALL-E, Stable Diffusion, etc. and regard it as stealing, but they view Copilot and GPT-3 as merely useful tools. I also know software devs who are extremely excited about AI art and GPT-3 but are outraged by Copilot.
For myself, I am skeptical of intellectual property in the first place. I say go for it.
When Microsoft steals all code on their platform and sells it, they get lauded. When "Open" AI steals thousands of copyrighted images and sells them, they get lauded.
I am skeptical of imaginary property myself, but fuck this one set of rules for the poor, another set of rules for the masses.
I haven't been following super closely but I don't know of any claims or examples where input images were recreated to a significant degree by stable diffusion.
A broadcaster of copyrighted works is not protected against infringement just because they expect viewers to only watch programming they own.
On the subject of trademarks the issue is as far as I know even more on the end user because the protections on them is around use in commerce and consumer confusion not about just recreating them like copyright protections.
