When I did the numbers I realized I would likely only save about $50=$100 (house, two cars, Motorcycle) and they dont do motorcycles so Id have to have a second insurer.
I canceled my NFL Ticket with Direct TV
Interesting, I had USAA insure my motorcycle (when I had it) without any issues. Maybe the state you're in affects this?
As to the OP, I'd bet USAA is probably looking to pull sponsorship. A LOT (read: Most) of the their clients are former or active duty military, as are their employees...
