I plan to write some tech blogs, where one of them showcases an application from GitHub without a license. Now I just forked it as a backup because I don't want my viewers can't find it someday if the original uploader deleted it.
Now instead of showing the original GitHub URL of the application, I put my fork URL, where I don't change any bit of it. Of cause I will cite the original URL as a backup link in my blog.
The question: Is it legal that I use my forked URL inside my blog (and only use the original GitHub URL as backup)? Since I don't have any right to the repo besides the right from GitHub of forking it.
PS: Now, I don't modify the repo itself at all. If any visitor from my blog click on GitHub to download. Any notice I need to share on my blog to protect myself?
