From the BBC article
"I am not suggesting you give us the code," the home secretary shot back, telling him: " I understand the principle of end-to-end encryption - it can't be unwrapped. That's what has been developed.
"What I am saying is the companies who are developing that should work with us."
It's not very clear what she means here. Work with them how? By decrypting messages? In which case, isn't that just giving the Home Office "the code"? (spoiler: yes it is, assuming she doesn't mean source code; and she probably doesn't mean source code, being Amber Rudd and all).
The whole thing smells like a ranty soundbite. Designed, presumably, to appeal to the Tory faithful at the annual conference. And to get Rudd a few column inches about being tough on terrorism while conveniently skipping over all the detail of how that might work. Perhaps it will also take the spotlight off her recent contempt of court travails.
Amber Rudd and the liberal-arts-educated political and Civil Service elite would do well to pay more attention and respect to technical experts generally. Rather than treading on toes every time she opens her mouth.
