Iain Duncan Smith claimed it led to people being bombarded with complex consent requests
I can see how Iain Duncan Smith might well find it rather hard to solve a "complex" problem like deciding which of the two buttons to press.
"I Agree...I Don't Agree....... it's just so confusing isn't it?"
Also doesn't realise that it makes him sound like Alan Partridge when he found an "additional costs" item on his hotel bill and then claimed he got confused when his tv asked him to confirm whether he wanted to watch the adult pay tv channel or not.
