Their concern is their IP is being inputted into Chat GPT and then being used to train it further. Imagine a scenario in which you ask it to help you with some kind of banking code and it spits out JPM proprietary code
Bingo that is proprietary information. That you are feeding into an AI used to gather information. shyt the equivalent of writing code for Lockheed Martin and sending it to some software engineers in China to help you write the code.
I am shocked folks ain't more worried about feeding info into Chat GPT.
