I started working on srctree 2 years ago because of how awful github has become. I don't think there's much creativity in this trend line... But the question was; "why is insulting people doing intellectual work bad". Not, "do you think the changes at github are creative", but I do think that the changes require a bit of intellectual work, and that no matter how shitty github has become, it's unreasonable to attack people when unprovoked.
I agree that people should be treated with dignity...but groupthink & herd mentality often strips people of their humanity.
So the criticism is really about culture & abstract attractors...not the individual people who often act rationally within the context of the system.
