Please don't spread fake news😅 Nobody stole nothing. As I already mentioned on one of the comments down below, Adobe Firefly is different from other AIs.
It actually pays for the content used for its training. Adobe says they : created a Firefly bonus compensation plan for all eligible Adobe Stock contributors whose content was used in the dataset training of the first commercially released Firefly model.
Here's a link to the source : https://helpx.adobe.com/stock/contributor/help/firefly-faq-for-adobe-stock-contributors.html#:~:text=Yes.,first%20commercially%20released%20Firefly%20model.
Plus, they just don't snatch resources from random places on the internet, they use adobe stock images, which as they said, they compensate the contributors, or they just use public domain images which are copyright free.
