I personally campaigned at the time the law was being debated. Met my local MP, even.
If I'd known about the idea of "inferential gap" at the time, my own effort might not have been completely ignored… though probably still wouldn't have changed the end result as I still don't know how to show lawmakers that their model of how computers and software functions has led to a law that exposed them, personally, to hostile actors.
How even do you explain to people with zero computer lessons that adding a new access mechanism increases the attack surface and makes hacking easier?
The politicians seem to see computers as magic boxes, presumably in much the same way and for much the same reason that I see Westminster debates and PMQs as 650 people who never grew out of tipsy university debating society life.
(And regardless of if it is fair for me to see them that way, that makes it hard to find the right combination of words to change their minds).
