Just like when demonstrating object oriented programming with trivial examples, DI suffers the same problem. DI, or Inversion of Control (the thing you want to achieve "through" DI), works best at scale, not with Hello World examples. When you work on a large code base with a large team you need some philosophy and principles to guide you. Decoupling is one of those things. Since Java is often used to build large software projects you will see these techniques being used and we therefore associate these things with Java (i.e. the Java bloat). Over the past few years it seems that PHP has become an "easier" Java and it's therefore only natural that these techniques and approaches are then also applied.
