This isn't held back by the bigger industries but by entrenched boundaries of responsibilities in the administration (defined in the regulations), data protection, and over-engineering.
Latest example: Warning the population. Instead of simply sending SMS to all active phones in an area, it has to be cell broadcast, which doesn't work on old phones. The reason seems to be (information in media is... limited) that sending SMS would not provide a way to send a cancel/warning-end message. That's only possible with cell broadcast. And that hasn't been used so far due to data protection concerns (there's a list of phones that have been warned, i.e. were in the affected area).
We cannot solve things the simple way.
