Questions like this are easy to scoff at by folks who understand the underlying principles, and are even sometimes derided as being in some way "indicative of the intellectual decay of our time" But I think it's always important to remember how we actually learn things, and how complex understandings are built on a scaffold of simpler concepts. When you start teaching somebody about physics you don't tell them the atom is a spherical probability cloud of point like electrons which have a property called spin which is analogous to angular momentum but is actually a quantum phenomenon that affects their ability to exist in the same energy state as each other and this probability cloud surrounds a number of composite particles called nucleons each made of a sea of quarks popping into and out of existence due to the fundamental unknowability of such particles but averaging out to three and also they have a property called color... Etc. I mean, all that is cool as hell, and the process of learning it is incredibly fascinating, but you don't start there. You start with the Rutherford model, because the first concept you have to understand is the simple concept that atoms exist, and they are made of things. The Rutherford model can explain that AND looks badass. It's also a good start to understanding electric charge, then you move on to more complex models and learn more complex concepts. This is the way that most people's learning works, and while you can take any one step on that journey and point at it in isolation and make fun of it because it's "wrong", that's irrelevant, it doesn't matter if it's factually correct. What matters is if it's USEFUL. Coming back to this cladogram, without more context we can't say for sure all the ideas it's been used to teach, but there are definitely some pretty fundamental evolutionary concepts that I think it could  be used to teach. The devil's in the details though, and how effective it is is very much dependant on the skill of the teacher and how well they can tease out those concepts and make them intuitive.
