This is an interesting case of open network versus private network interest. Multichoice (PayTV) does not want the standard settop boxes to have CA because it enables a competitor (e-TV) to run their business. Of course it is a valid question to ask “which CA”? And the actual choice is hardly ever a neutral onI. In some Nordig countries (Finland specifically) this was done with Conax in the past; all PayTV operators have equal access to the CA system.
The argument used by Multichoice may be valid: many CA systems have a cost for embedding. But the business model can usually be shifted to pricing the smartcard. Maybe a valid question is whether the access rights to the CA system are reasonable and equal, and.or whether Multichoice has a good erason to wish to select another CA or at least not the same CA as the standard one. The article gives to little background on these questions.
