The injection model
First sentence mentions Huawei and government fretting, putting me in mind of news today about a leak from UK government about future policy. The imbecility of our "leaders" once again staggers me.
Before your acrimonious divorce, your wife, as a GP, used to treat you herself.
For legal reasons it remains the case that if you die she will reap a large financial benefit.
You're under the weather, feeling rough and with a spot of painful gout.
Dropping the kids at her house one evening, she notes your condition and, with uncharacteristic sympathy, offers a powerful cocktail of vitamins injected straight into your jugular. She's done it before, in happier times, without harm.
This time, considering the bank balance and because you are a nasty suspicous type ... you regretfully demur.
But you do agree to a local analgesic injection into your burning, gouty toe. Because it's "non-core".
I suggest this admittedly clumsy analogy will illustrate even to the dimmest of the dim (politicians) why, if you don't trust a tech provider, the idea of allowing them only "non core" access as a way of securing your health is risibly stupid.
(Oh, and for those still arguing about why we might be sterilising ourselves of Chinese tech, I will simply repeat: Capabilities, not Intentions.)
