"Although the source code of the app is available, we cannot compile it, run it, and make it work without signing an agreement with Apple or Google. We do not find it compatible with the notion of open source." <-- Isnt this the case with every app?
See the yellow "important" box on https://developer.apple.com/documentation/exposurenotificati... for some more info. Not sure how this works on Android but I assume there is a similar permissions gate to prevent other apps accessing this feature.
I'm speculating but I suspect the agreement they're referring to is the agreement for Google's proprietary Play Services API. I believe it's possible to compile Android itself and regular non-Google-Play Android apps without agreeing to anything but the terms of the open-source licenses.
Change the system... honor open source principles.
If ivory tower thinking means, improved state of affairs, then.. ok... ? Call it whatever you want haha.
Some consequential parts of the protocol are implemented as a black box.
> A big part of the contact tracing protocol (which was originally the DP3T protocol) is implemented by Apple-Google in a part of the system called GAEN. This part has no available source code although the law requires disclosure of the source code of all components of the system.
Since the first point is separate from that, it must be referring to something else?!
