According to this article, "customers of Shutterstock's Creative Flow online design platform will now be able to create images based on text prompts, powered by OpenAI and Dall-E 2." Worthy of note is this: "Key to the feature... is that Shutterstock says the images are 'ready for licensing' right after they're made." So to be clear - you don't own the copyright on images you create using the service. They do. This is what they call "ethically created visuals".
