This system is a backdoor. We should not be surprised if adding a backdoor reduces pressure to add a backdoor. :) But in the US it isn't just a backdoor, it's an indirect violation of the user's 4th amendment rights. If the government ordered apple to perform this scanning, the scanning would be unlawful and the result would be inadmissible in court. It is only lawful because Apple performs it voluntarily (or at least that is the pretext maintained in court-- repeatedly Apple staff have maintained to me that the government is requiring them to do this). The government should not get the ability to execute unlawful searches simply because it's able to use soft power to coerce user trusted third parties to perform the searching on their behalf.
