Good in principle, not so good in execution
In principle, there should not be a window where kids can rack up in-app purchases without parental (or any device owners') consent. However, this settlement sounds a little like Big Brother strong-arming Apple. If the numbers shared are accurate, the FTC stands to gain quite a bit from this settlement. I suspect the issue could have been more fairly and appropriately dealt with, including penalties on those game "designers" who build junk games they give away in exchange for in-app purchases that are required for any kind of success.
