Secure endpoint software has to be non-commercial in that it has to be open source or otherwise trust-able by the public. Because it can&#x27;t be proprietary, it would be hard to sell under any circumstances. The major portals could create this software, or they could just provide documented interfaces.<p>To provide default-unbreakable encryption requires a combination of commercial services that enhance the UX of using strong encryption, like web-of-trust features in communications software that make it impractical to MITM communications and key exchange, and non-commercial software that secures communications payload.<p>So any effective ban would ban not only an Apple proprietary system that was secure, but also those non-commercial components that are a necessary part of a truly secure communications system. That&#x27;s where the overreach happens.
