It seems more like a politically-correct attitude to me, rather than a positive one.

Instead of just stating the problems and some possible solutions, it wraps it up with faux sentiment about "loving" GitHub, and making it sound like GitHub is a poor soul suffering from some medical condition.

GitHub is merely a tool, hopefully just one among many in any given developer's toolbox. It seems kind of weird to me to think of it as anything but a tool, and especially weird to tread so lightly or carefully when discussing its flaws.
