They are just design principles; I did not claim to have a well-planned design ready to go to market. Some operating systems make it harder to hide software than others; GNU/Linux makes hiding software more difficult than Windows or Mac OS X. Some computers are easier to reimage than others (e.g. special key sequences during the boot process will cause a "factory reset").
