well this is a choice the government has made, it's not a hard problem unless you expect perfection forever

but with all security stuff, the weak point is always the lazy user who won't tolerate even the tiniest sliver of inconvenience. so even if the government does have some hot shit secure chat an NSA furry cooked up, they likely wouldn't use it anyway because they couldn't have their family chat and top secret military chat in the same phone app
