Looking at these things without taking into account prior similar cases will lead to sub-optimal decisions, because if you don't take into account that similar stories have played out before, you'll have to take the industry's word for it that "this data will only be used to sell you stuff." And later you'll have to take the government's word for it that "we'll only use this to defend the border." And so on.
But we have seen these things play out before. That is why "First they came for..." was written. We can already predict how this going to go from here. And personally, I don't like the way it's going.
However, what is avoidable are fixed IDs like IMSI and IMEI that allow persistent tracking of the "same device" or "same user" across every tower. The routing functions of IMEI could easily be replaced with a nonce that changed for every registration. The billing functions of IMSI could be replaced with blinded tokens. And the persistent identity of phone numbers could be provided by independent parties like with email, ideally over a (non-wireless) mix network.
2. Why should I care? If they're gonna have a border we should equip them to protect it.
3. Why should I care? I haven't done anything wrong.
4. No seriously, I swear I didn't do anything wrong. I never went to those Union meetings. You can check my track!
