I would be amazed if anyone accepted this offer, it's not enough money to justify making every other job interview afterwards harder. I bet it's just a PR trick to make them look like better employers after the warehouse conditions were exposed.
How does it make other interviews harder? Saying you left because you felt the company wasn't a good fit for you and they offered you a sum of money that gave you a little leeway to plan your next move sounds perfectly reasonable to me.
Who says you have to have job interviews afterwards? I've known plenty of people who line up interviews before they actually quit, then only quit when they've got another job lined up.
