I own a Bolt (bought used) and have never activated OnStar, and I'm extremely unhappy to learn that it might be spying on me.

I did some reading when the NYT article came out, and found this, which explains how to install a terminator on the antenna to disable the cell connection: https://imgur.com/gallery/n00QKnH. If you go that route, it's probably prudent to make sure your car isn't connected to wifi, either. (Edit: looks like that guide came from here: https://www.reddit.com/r/BoltEV/comments/16h91a6/i_made_a_st...)

Apparently some Bolts newer than mine have a different fuse configuration that puts Bluetooth and OnStar on separate fuses: https://www.chevybolt.org/threads/remove-mobile-data-chip.33...

^ that Bolt forum thread also talks about some of the downsides of disabling the antenna (e.g. GPS won't work so your home/away charging settings don't work anymore).
