This isn't children sewing soccer balls with their teeth type of principles. This is a machine controlled by code the end user doesn't get access to building another thing the user actually buys that has no closed code in it. Who cares how the thing was built using whatever software to control the things to build the product? That software affects the end user in no way other than to produce the thing. That's like in an entirely different universe than running code on your computing device where you should be able to decide who/what/when/where type of questions. Telling a manufacturing company to do something regarding their software in their processes is out of this world insane. It is their software after all, so your freedom to run stuff your way should also reciprocate to them doing what they will with theirs.
