An opinion post from The Economist. One thing not often mentioned is that the 3G and 4G core are currently in a large part from Huawei so we should already be experienced in looking for signs of nefarious activity…:
[…] Britain’s decision matters: it is a member of the “Five Eyes” intelligence-sharing alliance led by America, and was one of the first Western economies in which Huawei built a presence. Britain also has experience of electronic spying and knows Huawei well. Far from being a betrayal, Britain’s approach, of using the firm’s gear on the edges of 5g networks, under close supervision, offers a sensible framework for limited commercial engagement while protecting Britain’s security and that of its allies.
