Background:
> Here, as in those other cases, the government had a search warrant for the device, but it was thwarted by the device’s lock screen in executing the search.
> The government cannot impose an unreasonable burden on Apple
And the case EFF cites to for that proposition holds: "We conclude, however, that the order issued here [requiring a telephone company to assist the FBI in wiretapping its customers] against respondent was clearly authorized by the All Writs Act and was consistent with the intent of Congress."
> and it cannot violate the Constitution.
Sure. But the fact that there's a warrant takes away your biggest Constitutional argument--the 4th amendment.
> What’s more, such an order would be unconstitutional. Code is speech, and forcing Apple to push backdoored updates would constitute “compelled speech” in violation of the First Amendment
So the government can't force Toyota to push a firmware update to fix faulty electronic throttles?
> government keeps pushing for “exceptional access” to encrypted devices and communications.
But that's the thing. It's not "exceptional." Since the founding, the compromise is that the government can get at nearly any place that might contain evidence, so long as it has a warrant. Digital privacy proponents are trying to move the goal line, limiting government power in unprecedented ways.
Note bene: I support pervasive encryption and oppose back doors.
