The solutions requiring constant internet connection are pushed by states and companies because they help cutting costs and gathering information. However, the users are often more vulnerable to the risks if the technology fails but have relatively little say.

The solutions that do much the same but require internet connection only once a day or even once an hour would be much more resilient and safe but currently there are few incentives for providers to develop and offer them.

The extreme situations like war or dictatorship are good awakening calls but it is easy to see there are lots of risks involved even if things would go rather smoothly otherwise.
