Step 1. Make a stock photos library for everyone to upload.
Step 2. Use that stock photo library to train your AI without letting users opt out. You couldn't remove photos without accepting the licence.
Step 3. Allow users to use AI generated art on said stock library, even further ignoring artists by regurgitating art from other models.
Step 4. Force new licences to users that use any file as potential training data.
Step 5. Act shocked when everyone is mad.
