Re: Why did they do it?
Personally, I'd want the option, mostly. If i'm too cheap or otherwise CBA to set up my own storage box, I can use theirs; fine. But when theirs inevitably goes down, or they decide to kill the service entirely (Here's looking at you, Google!), or my internet provider decides to take a week off?
I'm genuinely baffled why the manufacturers are trying to sell devices to people who are obviously security-concious and/or paranoid--and then not baking in secure options. You'd think that'd be like selling cars for people interested in personal transportation that cannot be started without having two neighbors and a representative from the company seated within?
