My serious question: Is this a way for the EU nations to quell public uprisings from fuel shortages by limiting network communications while not taking the blame for it?
No. They are talking about limited disruptions to limited areas due to planned load shedding. If your power and phone are out for 4-6 hours - is that going to suppress your ability to protest?
I know I'm not supposed to do this, but is this "concern trolling"? I can't see how you could get from A->B unless you're trying to rabble rouse?
It is not a fault, but a virtue to be suspicious of governments during times of protest. Does a 4 hour black out slow down protests? Probably not, but it does not stop countries like India from constantly doing so:
