Re: What is this long, angled, low friction thing I see before me?
Yes indeedy. I've said this many times - 1) Stop trying to make technology be the parent. I have two sons: one of almost 15 and one almost 9.
The 9yo rarely has unspupervised access to the internet and his games are age-proportional.
For the almost 15yo I am slightly less concerned because I have all of his passwords. He knows that I can, and do, randomly check what he's been up to.
That's the price he pays for the freedoms.
So....having got that first part of the argument out of the way (and here's a tip for the moronic parents and mumsnet types that believe this is necessary - put the computer/tablet etc where you can see it when it's in use) the second point, b) is, as others have called out - it's one step away from the Government saying things like "Oh expenses scandal? What expenses scandal? <click>"
Of course you can insert your own bit there for whatever they deem it necessary to "protect us from seeing".
We, as a nation, seem to be hell bent on sleep walking into 1984....it was a warning ffs not an instruction manual :(
