This overstates the difficulty of creating a JPEG. If you have an image editor on hand that isn't MS Paint (or you're using macOS, which has Preview), you merely need to export a JPEG and choose a low quality setting.
For a Windows user with no decent image editor or viewer installed, though, it could certainly be a hassle.

None of the things I listed are difficult. They just require the right tool and know how. For someone like me with Xubuntu, I had neither the tools nor know how for creating small jpegs. I didn't fell like wasting 30 minutes researching and I didn't feel like walking over to a different computer that has MSPaint.
Everything is trivial if you know how to do it off the top of your head. Generating white noise samples is trivial. UV-mapping a texture to a mesh is trivial. Soldering resisters to a PCB is trivial. Generating an ARM toolchain with Yocto Project is trivial.
Is it a crime that I didn't feel like researching a bunch of CLI tools I've never heard of to try to use an app I was only mildly curious about?
