Personally I think it does. The OP is highlighting an assumption that it appears to be the duty of the carrier to track and block content ("WhatsApp has ... problem"). Except that is exactly what carriers should not be doing, and what encryption protects against. Using carriers to track and block content is the definition of totalitarianism. I think child pornography is a hideous blight but stamping it out by shifting responsibility to the carrier is not the way forward.
