I’ve even experienced this in the 3D printing community, where I design a highly parametric model and put lots of effort into making all of the major dimensions and qualities parameterized and dynamically adjustable, with lots of bounds checking and value clamping, with all the parameters at the top of my scad file with comments explaining what each variable does.
And then someone comes along to remix my model, says I don’t want to install openscad, and just scales the entire output stl to change the dimensions, squashing all the features of the model in the process (instead of having the size gracefully adjust with all the features moving around to account), and leaving anybody starting from their work with a hard to remix mesh with no parameters.
You could end up working for a company that develops free software so that’s one way. My company develops an open source science tool and it’s free for anyone to hack on, run their own copy, and use for commercial purposes, but we sell support which usually seems to involve being paid to develop certain features and fix certain bugs, as well as advise on how to keep their system running smoothly.
