Reading most of these comments, it is as if people seriously don't remember SourceForge or Google Code... GitHub is a giant centralized hosting repository that has notable weaknesses in issue tracking and doesn't spend much time working on improving its core use case of code browsing--it doesn't even have a graph view for the commit log, which I'd argue is almost "table stakes", much less "great" features like fast and easy code search or cross reference support--and instead has been slowly attempting to build lock-in by mostly building new tie-ins to their platform like GitHub CI in attempt to reduce portability between hosting providers (which, at the end of the day, is what they are: a hosting provider that purposefully used the name of the tech it is built on to cause market confusion over whether it was git and then refuses to implement stuff like custom cname support to reduce portability). They will get disrupted by something, though it might take another five years... and then--just like with SourceForge and Google Code--everyone who hosted their projects on it instead of owning their URL will experience dead links as the ecosystem fragments for a bit before re-coalescing on "the new hotness as GitHub is now lame"; "such is the way" :/. At best, GitHub gets to remain forever as Facebook, slowly attempting to replicate the features of new disruptive players like TikTok in an attempt to reduce attrition. Man, I remember when everything was on SourceForge... ;P.
