It would also be trivially easy to construct something that squeezes the juice packets between, say, two wooden cutting boards, that would apply uniform pressure over a large surface area in the same way that the juicero does. Then, what do you have left? A bunch of features that I doubt people really care about, such as automatic disabling of packs (seriously, just send me an email) and reorder reminders?

A $8 tortilla press can do the job as well or better than this over-engineered piece of junk.

A $15 pasta roller can probably come pretty close.

I don't think a roller would work. The solids in the bag would settle to one side of the bag and form a clump. You would either need a ton of torque to drive the roller and smash the clump or a slip-roller.

If this discussion goes on for much longer there will be something even more complex than the device shown.

A double-roller system will probably have that problem, but twisting the bag in on itself and just torquing it will probably work, the bag's pressing against itself in a fairly uniform manner.

I wonder if you could get uniform pressure by putting the juice bag itself in some fluid, then pressurizing that? I mean obviously you could, but I don't know if you could get 15 bar or whatever they are going for using something relatively inexpensive.

(OTOH, it would be annoying if it exploded)

I think the main reason for the QR code is to discourage third-party juice packs.

Well that might be part of it, but the reason is because the juice had no preservatives so they will go bad. Honestly it would be a product failure if people were getting sick for using the bags after they've gone rotten

If only there were some simple way of indicating a date by which a food should be used. Maybe they could make it human-readable.

I highly doubt you can apply that much pressure without wooden boards breaking or warping.
