And water is wet.
Of course Brits are going to answer that they'd rather not have the government read their private correspondence. But at the same time there has been very little protest over draconian legislation in the UK like the Online Safety Act and RIPA Part 3 that cover just these aspects.
The Online Safety Act has broad support from the people of the UK from the left and right combined.
Nobody is stopping anyone protesting against it, but it is not imposed by some imaginary uniparty fascist regime, it is something people want.
