Ian Levy, when he was at NCSC spoke about "shame as a weapon against Big Tech". But he missed a crucial flaw - they do not give a fuck. Shame and ridicule only work in societies where people have dignity, self-respect, mutuality and care.
It's true that nobody has any reasonable expectation of privacy when using a Google smartphone. But the ruling talks about "willingly". What does "will" have to do with modern life where people are badgered incessantly to surrender their choice, boundaries, and dignity?
To exercise "will" these days, is quite a big deal, and usually means going against the flow and suffering some loss.
