Just seemed strange that the radio-frequency regulator would demand that 3rd-party selling platforms stop transactions but not also demand ISPs to de-auth them too.
Just suggests that the restrict them are BS or maybe spyware/intelligence related.
If I remember correctly the regulation is against these devices being sold in Canada if they're not authorized, not about them being used in Canada. It would be really unpopular with the ISPs anyways and our regulators are completely captured here in Canada so I don't see them doing it even if they had to.
But yeah the law in Canada about IC regulation touches upon sale, not use. Manufacturers, distributers and importers are held responsible, not users or carriers.
I don't know of any devices at all that get rejected on Canadian ISPs. Blocking Xiaomis would cause a lot of issues.
