I think the biggest travesty was that the Canadian government was unwilling (or unable) to go after Huawei (and China) for the damages that this attack caused. At this point, USA has almost completely destroyed Huawei's global consumer electronics business in retaliation for similar attacks on American companies[0][1]. There is no more such thing as a Huawei mobile phone, at least in western civilization.
That is the kind of response that I would expect. But I never heard about anything even close to that from the Canadian government.
