I do feel that GitHub's product development has been less exciting in recent years, but that's natural for any maturing platform. While I can't judge whether there are fewer talented people involved, I've noticed they haven't increased mistakes, and the platform continues to grow. It would be unfair to overlook the hard work that goes into maintaining GitHub and shipping new features (even if some of those features aren't to everyone's taste). I'm grateful for GitHub and hope it continues to thrive. Peace.
