...OK, actually I do see the connection. The suggestion is probably that if the technology is not totally open, you don't know how much power you're giving away (the manufacturers could be cooperating secretly with the authorities). But if you really feel like this, all you need to do is refrain from using your iClosedDevice for any type of work or communication that you wouldn't trust in the hands of the manufacturers/authorities.
... And OK, I see the point that we need to support the alternative methods or else their won't be any when we need them. It's just the either/or sentiment that bugs me.
