This is probably the most textbook spin I've ever seen. It's as if their PR firm didn't even try.

These robots are obviously being deployed to increase margins.

Personally I would have went for the "adding more value" angle, either by suggesting to the customer that "Your favourite product is more likely to be on shelves", or positioning these robots as "helpers" to shelf-stackers.
