[I do not work for the NHS]
Because you need to be very careful rolling this shit out to make sure you don't fuck up everything else.
The NHS will have thousands of applications and system to test before it can roll out something as invasive as security software.
I'm sure it makes a good headline for you and a nice soundbite for the politicians but you should ethically consider the technicians you are kicking in the bollocks with titles like this.
You be quick enough to flash up a story if they'd delayed operations because a botched roll out of ETDS to 6 millions devices borked 50% of them.
Ivory towers and glass houses etc etc
