"My supplier did it" is not a valid excuse for ducking responsibility. If you put the demand on your supplier, and they do an unethical thing to supply that demand, then part of the blame lies on you for not having (a) done the due diligence to ensure that your supplier was above board and (b) checking that they could, in fact, meet your demand without doing illegal or unethical things. If you have no responsibility for what your suppliers do, then you could delegate practically any negative externality of your corporate practice to your suppliers. The argument here is that Cadbury is effectively turning a blind eye (intentionally or negligently) to what their supplier is doing to meet demand. For an example of companies which actually do care about their responsibility all the way up and down the supply chain, go have a look at the Supplier Responsibility statements and reports put out by big companies like Samsung (https://www.samsung.com/us/aboutsamsung/sustainability/supply-chain/ https://www.samsung.com/us/aboutsamsung/sustainability/suppl...) and Apple (https://www.apple.com/supplier-responsibility/ https://www.apple.com/supplier-responsibility/).
