A TCN can only compel a targeted capability where doing so does not require introduction of a systemic weakness. If the system is secured in such a way that the targeted capability isn't possible (e.g. open-source project with e2e encryption and verifiable builds), the government cannot compel introduction of a systemic weakness (e.g. stop using verifiable builds) to make it possible. My suggestion is that Apple/Google build their software such that it is systemically secure against targeted attacks.
