Huawei wanting a plant next door to a military drone manufacturer is a different matter.
However backbone infrastructure was always designed to be simple in an attempt for the highest security, which I believe is correct. TalkTalk have introduced virus scanning (guaranteed to have even non intentional security flaws) with praise from the UK government. The idea is sound as it can thwart malware for home users and give parents better control however two things have been missed and allowed.
Any critical infrastructure should be simple and/or open to complete scrutiny by being veritably open source.
Any security reducing proxy put in place for home users must be opt-in and not be compulsory for all users even business customers who are not able or want to use TalkTalks Homesafe service.
It is likely illegal for multiple reasons but who would sue them.
