It would be nice if there was an explicit CC license, but ArXiv has a perpetual license to distribute it, and you can link to ArXiv. Why would you host the paper yourself?

Edit: The code has been published as well, under the MIT license. https://github.com/openai/improved-gan

Why? There could be many reasons, but mine is because I'm doing a small Arxiv alternative. Unfortunately no license means closed with copyright... which I expected OpenAI to know and handle
