I mean the fish rots from the head, but at the end of the day that rot translates into an engineering culture that doesn't value craftsmanship and quality. Every github product I've used reeks from sloppiness and poor architecture.

That's not to say they don't have people who can build good things. They built the standard for code distribution after all. But you can't help but recognize so much of it is duct taped together to ship instead of crafted and architected with intent behind major decisions that allow the small shit to just work. If you've ever worked on a similar project that evolved that way, you know the feeling.
