Why are Hershey's Kisses aerated? Like my yard?

Can someone please explain Hershey’s new aerated Kisses to me? Are we not just paying the same amount to have air whipped into our chocolate, saving money for Hershey’s? I expected them to be like 3 Musketeers inside, but there are just air pockets. It's like when my husband uses the aerator on our yard to keep the grass healthy. Do they have a mini aerator that they run over chocolate to make tiny holes in it?
