"the politically fraught task of policing home-grown implementations"
Now that I can understand. And we have a magnificent example, don't we, NHS ?
I do prefer that the two major players get their teams on this issue and iron out a common solution. I like that they say that no data goes back either of them, but I'll wait until the experts demonstrate that that is true.
In any case, I do believe that Google & Apple (Googapple ?) are less of a risk than some local company who got the job because the CEO goes golfing with the minister's brother.
Plus, at least the techs in both companies know exactly what their platform can do and how to call on it most efficiently. Knowing how to program an app for a mobile platform does not mean you know how to do the job using the least amount of power possible.
So good on Googapple. Let's just keep in mind the age-old adage : trust, but verify.
