Security shouldn’t be a niche use case. There’s a constant trickle of CVEs, and spyware vendors are known to abuse these exploits in their software. All this on devices that are reachable in the US through a text or MMS, sent to an easily located 10 digit number that isn’t easily changed. These are devices that people now use for all kinds of sensitive tasks!

Security should be the number one priority, frankly. Graphene has shown that this is possible, and they have tried multiple times to get Google to integrate their work.
