It's fairly well spelled out in previous statements where Smed explained the issue was with SC accumulation and tax liability. Basically for accounting purposes they aren't able to list the funds as available for use until the SC bought with them is actually spent, which means there's a whole lot of money on the books that SOE can't do a thing with (but still owe taxes on). As some have pointed out, the 500 "Free" SC was never free, but was a benefit of membership - which means part of the paid subscriptions each month were getting locked up until the benefit was redeemed. So they are requiring the funds be /claimed every month to ensure the people getting it are people who want and will use it. If the SC could accumulate in your /claim window, then it's still accumulating and the cash equivalent from it is still locked up on the books. By putting a limit on it (1 item only, or must be redeemed by x date), it becomes more like a $5 off coupon for a store you have a club card with. If you claim it within that time, the item claimed (in this case the SC) is yours and you can sit on it as long as you like. If you don't, the coupon is unredeemed and the funds are released to the company's accounts when the limit expires.
