APIs are critical to a platform's value, so think of interoperabilty like this as a transfer of that value from the platforms' owners to app developers and users.
And here's the documentation of the contact tracing API framework, along with the specs for the cryptographic and Bluetooth protocols involved. https://covid19-static.cdn-apple.com/applications/covid19/current/static/contact-tracing/
Takes like this, while udnerstandable and expected, don't seem warranted (or at least not yet). https://twitter.com/aral/status/1248670699251785729

Or it's actually not, and it could be improved upon. https://twitter.com/cnoanalysis/status/1248670689650831362
Matt's observations track with Moxie's. https://twitter.com/pwnallthethings/status/1248727100921729029
I think these observations are correct, too. https://twitter.com/ncweaver/status/1248744472763969536
Another good breakdown of the contact tracing framework announced by Apple and Google. https://twitter.com/ohunt/status/1248718343005036544
