It sounds like idiotic clickbait, but it actually isn't.
The method is actually quite simple: You will only be introduced to the things you NEED in order to get started with composing music. That means that you miss out on the in-depth theoretical explantions and long lessons on why things are the way that they are.
There is a time and place for that. But the goal for this course is to get you started writing music as fast as possible using the coolest instrument of all - the guitar.
