Glad I work for a company where the CEO pays for everyones ChatGPT Plus for the devs. If you think your code is special then you're wrong.
Unless your company really has nothing to hide, it's easy to accidentally dump a company secret or an API key in a chat session. Of course if everyone is aware of this and constantly careful then you may be OK.
If you're copy pasting API keys or such into ANYTHING, you probably shouldn't be a programmer to begin with.
It's like people who use root account key/secret credentials in their codebase. It's not AWSs fault you got a large bill or got hacked, its because you're dumb.
Not my place legally or ethically to share code with 3rd parties that I've been paid to read and write.
Your code is not special, but customers data may be. Also, some companies needs to comply to various certifications, and proven leak of source code that was put into some third party tool may be a reason to revoke such certification. Which can cause a serious financial harm to a given company, as it can lead to ex. losing government clients.
This is just the tip of the iceberg.
And if you think that there is no special code then you're wrong.
Lots of code expresses buisness strategy that is a competitive advantage/ sensitive.
My org has done a risk assessment and accepted the risk of using such tools; arguing there is no risk is short sighted.
It literally is exactly that. You don't think the code a business creates is "business data"?
