Abstraction is at the core of programming... complaining about people not "properly managing mutable state" is like complaining about choosing Java over C because they're not "properly" managing memory and instead using a garbage collector. Maximizing hardware performance is, truth be told, largely irrelevant for the vast majority of applications. If they can meet their goals/deadlines/whatever, you can call them lazy, but I think most would call them efficient. Though I must admit, every time my browser lags when viewing what SHOULD be a static site, I do die a little inside.
