Nokia should have been nationalized. It doesn't need to be a local autarky. It could be something more similar to Comintern.

I'm sympathetic to your arguments but I'm fairly sure that nationalizing Nokia would not have staved off the inevitable, though, selling it to MS certainly accelerated the fall.

I still have my trusty N-800 tough, and I expect it will last another decade but that phone was made well after the Nokia brand effectively ceased to exist and is more of a reboot than a successful pivot. Clearly I'm not the 'ideal consumer' but I'm also the exception, I don't know anybody around me except for my 90 year old uncle who still has one of these and even he's been eying a smartphone.
