All of the features they use are easily changed in software. And not "an expert can get to hidden settings to change those aspects", they're as fundamental to the process of printing a model as selecting single or double sided is when printing from a conventional paper printer. Depending on what I'm printing I'll choose anywhere from ~.04 to ~.24mm layer heights, increase or decrease the speed or temperature, choose from any of ~10 spools of filament I have in a drawer, vary the infill density or pattern, (or somewhat less commonly) change the top/bottom layer pattern. It's not like a Star Trek replicator where you push the "gun" button, you have to find the model and tweak your settings, and there won't be any single set of settings consistently used on any printer unless the user is only printing a single model repeatedly.
