Cool app, could be very important
Personally, I support the COVIDSafe idea. We don't have a vaccination yet, so contact tracing is important. The app is very easy to install and innocuous to use. Since it could save lives, great, though I would prefer for it not to use AWS. This puts our data under the control of a third party and possibly a foreign government. Really hard to understand why this is necessary except as a short-term expedient, as there is open source software and locally owned hardware that could be readily used for the data storage required, which doesn't appear huge.
