OpenAI is working on a tool to watermark AI-generated text to prevent misuse

Open alternatives, like GPT2, have already been released under an MIT license. Community language model trained on NSFW text already exist as well. In my opinion, a move like this would only push away most people in the long term. Given the choice between a non-censored good enough model, and a censored great model, I would choose the good enough model for 99% of my long term projects.
Others will emerge.
If I know you put steganography in there I can make damn sure it doesn't stay in, for small enough chunks of text.
