I disagree. I specifically cited in the context of the apps made. The contact tracing that was in effect for COVID was far more comprehensive.
If you didn't get that message, you likely were not paying attention. I knew people that were using disinfecting wipes on their groceries because of contact tracing. Eg, they couldn't know what or who made contact with their products prior to having them, so they did the right thing in the context of contact tracing and sanitized the items to the best of their ability.
This wasn't uncommon among those that actually wanted to avoid the virus.
