For me it's both about the privacy and vulnerabilities in the Bluetooth stack such as https://www.armis.com/blueborne/ https://www.armis.com/blueborne/ According to the article, you need Sep 9 2017 security patch level, but my 5 year old phone is on Sep 1 2017 level. No way I'm going to have Bluetooth turned on in untrusted areas. While I'm unlikely to get hacked on the street or in a store, it gets more likely in places like a bus or a train (while commuting).
