Yeah, that was my take. Initial packaging for shipping and warehouse storage assumes the equipment will be moved from one type of environment to another several times, warehouse to warehouse, warehouse to truck, travel through wet/hot/cold/dry conditions, store shelves, etc. The silica helped neutralize the environmental changes inherent in shipping. Long-term storage in a climate controlled environment was a different matter. Besides the grease, the silica can dry out leather, leatherette, glues, etc.
