I think this is a very well written article with great examples.

However, I would give the same criticism as I would to the SRP (Single Responsibility Principle): What exactly is a "reason to change"?

In my experience, it is rarely as clear as in the examples that were given. This vagueness of the SRP has always bothered me. In my opinion, this problem invalidates (or at least weakens) the entire SOLID concept and many of the Gang of Four patterns with it.
