I do understand where the confusion is stemming from, but taking the time to properly learn the clash between Leibniz and Lagrange is very important. It makes a lot of sense to use one versus the other in specific cases. You might be able to protest by saying there are certain cases where the differential operator is treated like a fraction, but not only would I call this a rarity but also a cheat to what is really happening (the chain rule comes to mind). I do think it's cool to think of analogies that could include notation changes for students in early calculus classes though.

Fixing the notation would be great, saving numerous future generations from confusion.

Getting agreement to do this is difficult. Short of laying it down in the law as part of a treaty (throw it in with WTO or Berne copyright?) there doesn't seem to be a way to make the change happen. Nobody wants to buy the calculus book with weird non-standard notation. It would be like a trigonometry book with the symbols Feynman invented in high school.

We're more likely to get serious mathematicians calling equations "math sentences".

I am in favor of notational changes, but calling this a 'flaw' is simply wrong, and the teacher profiled should correct the journal allowing his idea to be misrepresented.
