I'd argue that there is, but we are just too used to the Lightroom or Photoshop way of thinking/workflow. We don't entertain other programs because it is difficult to learn a new way of doing things and return to a place of competency. And the less people use a piece of software, the less there will be documentation to help others learn.

I'm not sure if its a conspiracy theory or verified, but I do think that Adobe were okay with people (amateurs) pirating their software. We didn't have the money to pay for it anyway, but it got us to become proficient at using Photoshop so that when we eventually had money, we were locked in.
