Saving an additional $600 per patient is significant for a country as poor as Egypt. The existence of an even cheaper alternative strengthens the Egyptian government's negotiating position for agreements going forward. Prices may be re-negotiated further downward in light of this new development.
As a rough analogy: consider the effect of sci-hub on recent negotiations between universities subscribing to academic journals and the journals' publishers. Even if the universities do not openly embrace/endorse sci-hub, the existence of an unlicensed near-substitute for the licensed product has strengthened the negotiating position of the universities.
If that hadn't happened I would agree that the Egyptian gov't could probably care less if someone broke the patent.
