I think it's important to contextualize the situation. The Adobe TOS were updated, and people where understandably concerned over the rights Adobe now has over private customer data. The biggest issue was this part: "Licenses to Your Content. Solely for the purposes of operating or improving the Services and Software, you grant us a non-exclusive, worldwide, royalty-free sublicensable, license, to use, reproduce, publicly display, distribute, modify, create derivative works based on, publicly perform, and translate the Content."

People looked at this and immediately assumed this was added to allow Adobe to train models with people's private work.

Adobe has now updated their TOS, but this was a breach of trust.

Either way, in the end, this potential AI threat is just another reason to not store stuff in the "cloud".
