As I and others have pointed out multiple times, this is not a decision
that is in Cox's hands. It is a requirement placed on Cox by 3rd party
content owners. The requirement is very simple: in order to distribute
content X from content provider P, where P requires that X be protected by
DRM/CP system S, then Cox must ensure that what is delivered to its
customers is S(X). Of course Cox (and other commercial video providers)
routinely talk with content owners and may suggest they choose ClearKey for
S, but we can only make that suggestion, and not mandate or enforce it.
