What’s stopping people from doing that today is network effects. There are enough differences today between bsd coreutils and gnu coreutils that substituting one for the other doesn’t work out of the box.

The chain of events that would cause a problem are: due to Ubuntu popularity rust MIT core utils overtakes gnu coreutils and people drop support for gnu coreutils, then a large and we’ll funded corporate entity could privately fork rust coreutils and lock people in.

There’s a lot of manual calibration on ender 3’s I would not suggest taking it apart until you are more comfortable with the machine and then only if you really needed to do that.

Another reason that star count is a terrible metric for quality / authenticity. Fake stars are a huge problem that not a lot of people take seriously.
