This is true for any Android app requiring Bluetooth communication, not sure about iOS. An app might be able to figure where you are at based on the Bluetooth beacons (or any wireless) devices around. Hence treating it as a location permission as well.
This has been changed starting with Android 12 where they have specific Bluetooth permissions that filter out Bluetooth beacons. But it will probably take while before apps update using the new permission

I always dislike this take because it pretends the US doesn’t have this exact issue. I’ve known people with less than ideal insurance who had very few doctors to pick from in-network and would take months to get an appointment.
Long wait times still happens in the US. Just like it can happen in public healthcare.
