At the end of October, the RIAA motivated the closure of the repository which YouTube-DL I was using on GitHub. He did so with a letter in which he assured that he could take legal action against its developers, since the software was being used to download protected content. Now, less than a month later, the repository has been restored, and it looks like it will continue to do so for a long time, as GitHub aims to position itself on the developer side.
La removal from repository YouTube-DL and many others who used its code was automatic, so many complained. Among the complaints, he highlighted the Electronic Frontier Foundation (EFF), who, among other things, says that the software itself is not the problem, since its function is to download videos and this can also be legal. So GitHub seems to think so, at least after the code was modified by changing a few lines that seemed to be entirely at fault.
YouTube-DL modifies (very little) code to be legal
So and as they reported, so that YouTube-DL, or more specifically its repository, would go back to GitHub, you just had to remove from your code some references that used as an example. In these examples, the software mentioned three songs, and that is what they have modified and, in theory, has become legal.
GitHub says that, from now on, what happened with this software to download videos will be more difficult, since they will improve the process of decommissioning the code. Among the measures they will take, they will review each and every one of the claims, and whenever possible they will position themselves on behalf of the developer.
So if you were a YouTube-DL user and you were worried that the RIAA would prevent you from using your favorite tool, calm down, at least for now. He's back, and it seems he's done it to stay.
