It's discussed on Whirlpool:
Adobe break ur NDAs via PShop and Lightroom terms. - Retouching - Photography - Whirlpool Forums
In a disturbing policy change, Adobe will not let users continue to use PhotoShop or Lightroom without first accepting new terms that give Adobe automated and manual access to your imagery.
All files stored in the Adobe Cloud, and any file where Content Aware or Generative Fill are used, is likely to be transmitted to Adobe where they can review and use as they please (ie, to train their AI models).
This will greatly concern commercial users who have signed NDAs with their clients.
Your portrait customers might not be too thrilled with their likenesses being used to power AI image generation either. There is seemingly no way to opt-out this time.
