It's the first such flag-raise I've seen. Security researchers talk about protections from state actors all the time, and there are tools which support that... but this is the first public announcement, and tool, from a corporation with more spare, unrestricted capital than many countries. It comes at a time when multiple nation states are competing for energy and food security; and Apple are throwing up a flag for a security-security fight (or maybe data-security). This is not just handy tech, it's full-on cultural zeitgeist stuff. Amazing.
