"With no disclosure?"

Why do you have an expectation that a company will disclose to you when they use AI for their copywriting? Do you want them to disclose the software they used to draft and publish? If a manager reviewed the blog post before it went live?

Using words written by other people without disclosure has always been frowned upon. It's called plagiarism.

Plagiarism is bad for a lot of reasons, all of which also apply to the undisclosed use of generative AI.

Why not just publish the prompt? I can then take an LLM of my taste to reformat it the way I want.

Basically, I'm asking for open source blogging!
