I sell photos on Adobe Stock. They never properly asked me permission to train on my photos. The whole thing was opt-out not opt-in. Leaving Adobe Stock is not an option either as Adobe, like most stock services, continues to sell your images even if you purge and delete your account. Getting them properly removed is a agonizing, teeth-pulling experience with customer support and not even guaranteed to work.
So Adobe can take their “ethical, non-exploitative” AI and shove it up their ass. As always, artists continue to be exploited and abused for profit.
