Just because people don't agree with you doesn't mean they are "on the company payroll" ... 
Why doesn't SanDisk include Rockbox on the Clips? Because it has its own firmware, which is just fine and dandy. And companies like SanDisk rarely include 3rd-party software like Rockbox, over which they don't have control--it could be a support nightmare, among other things.
Sorry that you don't want to read and follow the Rockbox manual--the installation section, for automatic installation, is just a few paragraphs long. But that's your choice--just don't blame Rockbox when you can't install, and people have pointed you to how to do it, easily.
Personally, I don't get it--but as you said, let it be.
