Parliament firmly rejected rules which would force companies to scan huge volumes of people’s private messages – instead now requiring there to be reasonable suspicion

One of the main concerns was that end-to-end encryption would be effectively prohibited, not just "undermined." With respect to that, there is no difference between mass scanning of people's private messages and selective scanning of people's private messages based on suspicion. If you have strong end-to-end encryption both are equally impossible.

That this is so often misunderstood or neglected in statements like this one is worrying. According to Patrick Breyer's comments though, "End-to-end encrypted messengers are exempted."
