Call a spade a spade
One of the mistakes the ISPs have made here is to go along with the govt's anodyne vocabulary. On the first mention of "filters" they should have added "in other words a database" and then used that term in the rest of their submission. It's likely that the general media would pick up on this fairly quickly and given that the term is pretty toxic in this context the gov't would quickly have found itself dragged into defending the term and getting the whole thing more and more toxic publicity.
