I think you are vastly underestimating how much effort would be required to create software with similar feature sets to what Adobe's has.

I gladly pay them $10 a month for Photoshop and Lightroom and photography for me is just a hobby, not my job. There are free and paid but lower-cost sorta-work-alikes to both of those apps (and I even use them sometimes -- RawTherapee in particularly has some nice features), but nothing I've tried free or otherwise comes close to the overall feature set in those two packages.
