youtube-dl is an application, there's no benefit for the author to publish it there. I also checked PyPI repo and looking at it I don't think it is published, there are few that look like might be it, but looking at them, they feel like something that would install something nasty on your computer. As a somebody who relies on PyPI for development, I want them to store all kinds of data that would discourage PyPI to be used for any shady purpose. Also perhaps there's a better example than youtube-dl, as they really don't do anything illegal. Yes their github repo was taken by DMCA request but then it was reinstated back. The GitHub spin it that they are standing up for developers, but the DMCA was just frivolous. I guess, still good for them, because they could just take it down and do nothing.
