The current 2 hour limit (which is now 25 hours in Europe) is a legacy of privacy concerns. If pilots are concerned that their bosses would make a habit of yanking longer CVR units to micromanage what goes on in the cockpit (or using events several hours before an incident to somehow push blame onto the pilot for an it), they’d love the idea of it being beamed to a remote location. Yes, I’m sure there could be complicated byzantine cryptographic scheme that would theoretically solve it, but not sure they’d trust it.

There’s also bandwidth and satellite coverage not being magic of course.
