The easiest way to combat this is to put your model behind an API and filter queries (midjourney, OpenAI) or just not make it available (Google). The tradeoff is that you're paying for everyone's compute.

I guess SD is betting on saving $ on compute being more important in this space than the ability to gatekeep certain queries. And the tradeoff is that you need to do nsfw filtering in your released model.

It will be interesting to see who's right in 2 years.
