They likely do but to what detail? Should they have a line-by-line item of each employee being paid into their bank account each week? Apple can only give guidelines and draw contractual terms. If a supplier is in breach then Apple can go ahead and break the contract and that supplier would lose out on a lot more than just the contract (as is the case here). But to hold Apple accountable for the actions of this company (and it may have only been the finance team being pushed by say, a CFO to show profitability for a quarter before a promotion or something) seems out-of-the-ordinary and unreasonable. They're an easy target but you have to put the bias aside with Apple.
