method_missing is a tiny offense compared to what was getting popular at one point - creating classes by forking metaclass and injecting methods into... without knowing you're doing so (something IIRC got lost between people there...)

Result was objects that shared no structure, no field

Do you mean the class << self pattern?

That's what I thought as well. If someone's opening metaclasses to define singleton methods they probably know all about the Ruby object model. I don't see how it could be done "without knowing you're doing so".

The people who did it first did understand the meta model.

Unfortunately some people started following without full understanding. I wasn't at forefront of things back then, so I only noticed when the people who did know better started to writing about abuse of this technique.
