Why? It’s a valid concern in my opinion. You’re feeding OpenAI your intellectual property and just hoping they don’t do anything with it. I have the same concerns with Microsoft’s TypeScript playground
At the size of Samsung that's just an impossible move, and it's easier to blanket ban a problematic service and have employee request exceptions justifying their use case.
BTW I've been in companies that blanket ban posting stuff online, and got posts security reviewed when asking help on vendor community forums. That's totally a thing.
Personally I haven't used GPT much so I wouldn't mind, but banning copilot would make me reconsider.
