Considering the vengeance with which cryptobackdoors, or other forms of regulation into tautological-fail limitations, are pursued over and over again (case in point: The soon luckily carved out surrender (to Monay) monkeys [case in point: anyone who has seriously tried an invasion, succeeded handsomely]), it may be worthwhile to re-consider what the current situation is. As depicted in the following:
In which D is what governments et al can’t stand. Yes, it’s that big; pushing all other categories into corners.
Where C is also small, and probably shrinking fast. And B is known; maybe not empty but through its character and the knowledge of it as cracked-all-around part, hardly used if ever, by n00bs only.
And A is what governments want for themselves, but know they can’t have or it will quickly move to B — probably without governments’ knowing of this shift…
And all, vulnerable to the XKCD ‘hack’:
Against which no backdoor-for-governments-only policy will help.
