I have my phone running grapheneos set to automatiically switch off Bluetooth after not being used for 5 mins. Makes life easier for sure.

The project was heavily assisted by AI

just by having Bluetooth enabled on our devices.

Which is why i do not. Not in public at least.

Tldr: Bluetooth isn’t entirely the problem. The problem is manufacturers who don’t add privacy features like rotating identifiers into their Bluetooth enabled devices. Many smartphones are doing this these days.

E.g. modern non-cheap devices (iphone, pixel, general higher level android, airpods, apple watches, other modern headphones etc.) have those, and are not really track able like this.
