This tracing program is not intended to harm people. But to help with tracing COVID19 carriers. If we turn it off, why do we even want to use a phone in the first place? Our privacy is important. Still, turning it off will only just make the world not so much better with the coronavirus still at large.
Apple has allowed us to turn it off. That's a sign that they aren't doing this for their own benefit. Just please don't turn it off because you think your information is not safe. Do something for the world and contribute to fighting this pandemic.
