I don't believe there is a single real reason for complexity in building software. Nor was the reason given in the article fake, for that matter. In my experience, pkgsCross in Nixpkgs actually does make cross compiling a whole lot easier compared to other solutions. That's because a lot of the time, the techniques explained in the article allows existing packages to be cross compiled without any modifications. Even in cases where modifications are required, it saves a ton of work. Given the amount of packages in Nixpkgs, there's much less dependencies that you have to deal with.
