This is also pretty much the CAA's guidance* in that lithium battery powered items 'should' be carried in the cabin or switched off if out in the hold. Of course I'm sure whoever came up with the ban on them in the cabin area consulted fully with the CAA and didn't completely ignore the advice of the people who're supposed to deal with flight safety...

Not hugely surprising they can be stricter than EASA but not more lenient.
