Are you saying they should become a new root CA? That is a huge amount of work, and would require them to convince all browsers and OS's to make them a root CA, which many would be reluctant to do.
Legitimate uses of this would be things like government or military departments intercepting traffic from their own network.
As explained elsewhere in this thread, they have a history of working with regimes where they want to intercept the traffic of the general public in countries.
