Apple & Google's annoucement provides HUGE support for #DP3T against centralised solutions, which *no longer work* under it. The API they specify lets devices to query list of IDs they have seen, but NOT access them to upload them to a central server. https://www.apple.com/newsroom/2020/04/apple-and-google-partner-on-covid-19-contact-tracing-technology/

Apple and Google partner on COVID-19 contact tracing technology

Apple and Google announce a joint effort to help governments and health agencies reduce the spread of the virus, with user privacy central to the design.

The specification they lay out for their own proposal is extremely close to the published #DP3T 'low cost' design.

The consequence is that if the apps from the UK's NHS or German government want to work properly on new iPhones or Androids, people will have to leave them on (!) in their pockets.

(assuming they do not adopt #DP3T)

Here is a comic for how #DP3T works.
