Maybe something changed, but DSC was not yet profitable, so concluding that their service is a big win is premature. DSC was still burning cash which is important to consider in determining if they were sustainable.

The sale is a win for investors if they ended up with a good ROI. The article says the DSC brand cost $57m, but I've frequently seen numbers closer to $200m.

DSC alone may not have lasted, but if it has access to Unilever's product lines and resources, it can move beyond razors.
