I think data collection on buying patterns and purchase history, I can live with, but idea of real-time location tracking is problematic and i think really blurs the lines of privacy laws. I don't care what people do on the streets in in their bedrooms as long as it's not a threat to public or safety. I understand contract tracing can help, but I think we're well past that, and won't be truly effective until the number of active cases is quite small.
