I guess some people's point is that if the automated restrictions that come with those aren't used maliciously or commonly problematic, it shouldn't really be a big deal for it to exist. In fact, that they do exist is probably a good thing because it prevents amateurs from making potentially hazardous mistakes, given there really aren't any other controls on who can operate them.
From the sound of your initial post, it sounded like you were primarily building your own to evade these automated restrictions, but I'm going to assume you're more of an enthusiast and just don't add those features to what you build, and you build things for that intrinsic joy and customizability. If true, I think given your level of familiarity and expertise, that feels generally reasonable.
It probably has to do with the inability/expense of the facility to be able to properly secure outside food against other more serious kinds of contraband.
