Simple answer: Because the stupid hipsters try to change a simple concept of a state machine into MVC hell. More complicated answer: The weak side of the open source world is that it attracts a lot of developers with big egos who think that their fancy solution to a situation without problems is the best one. And they all compete with their too big egos and complicate our open source world. Real answer: too much memory, this causes people to come up with too complex systems as there is hardly a limit to their dreams, real inspiration comes from dealing with limits. That is why programs from yesteryear are often so good when looking at what they do within their constraints.
