I just created and maintain a little Android library (a very rewarding experience by the way) so most of the complaints about Github doesnt really apply to me because the size and reach of my project (I understand the point perfectly though). But I read some complaints about the users and the issues they tend to open and I fully agree. They are a minority but I can't only imagine what people with bigger projects have…
You can also run JitPack on-premises and have full control over build artifacts.
