Yeah countries and states are relatively happy with the non-privacy systems as they "work".
My principle problem is I cannot see this system "working" to the satisfaction of the seemingly incessant voices who don't want a child to see something that they shouldn't, where "something" is nebulous and seems to change with who you ask and at regular intervals.
I'm probably very jaded - I'd love to be proven wrong and this system works as a least worst option, but I'm in the UK and we recently seem hell bent on choosing the worst option offered.
