It's really optimistic to think mass rollout of Apple/Google protocol wouldn't be abused. Once government makes it compulsory to use such app in some scenarios (and society actually agrees to do that instead of protesting it en masse) it's over. There's nothing fundamentally stopping government from later changing the technical mechanism ("Please install our national app; it's more trustworthy than foreign megacorps"). Good percentage of society is not technical literate enough to differentiate between "brilliant Bluetooth solution" and "dumber contact tracing relying on data brokers"; for many people that's just implementation detail on the same level as new UI.

Apple/Google pushing their specific privacy preserving implementation of exposure notifications out via an OS update is not the same as a government mandating surveillance app installs.

The existence of the first does not lead to the second.

The implementation was only privacy-preserving in an idealistic World in which governments wouldn't mandate uploading of the beacon keys.

It's another example of the persistent, naive belief amongst technologists that clever implementation can trump legislation.
