Who would support darknets?
1) Darknets are used by dissidents opposed to their government, (a crime in their country)
2) By people trying to get around censor-walls like the great wall of China (a crime in China)
3) By people afraid of surveillance (a real danger in the UK)
4) By criminals
So, a random man rings you up and asks you if you support darknets.
Which of those 4 groups would answer "yes" to that? Nobody would answer yes to that! Are you shitting me?? It would flag you for surveillance, for arrest...
Silk road was a canary, a dead one. First thing a dissident would do is check the canaries to see how healthy they are, and they're dead, not pining for fjords, dead. Hence no viable darknets and no way to protect free speech.
Apple are right to protect their users free speech, because asking people if they support government snooping on the internet, is not asking them if they support government snooping on THEM. The question is chosen to drive an agenda not target the main issue.
