"Why would they risk people not adopting the app due to privacy concerns"
Because they could require people to use it, the may have to anyhow. Also - most people are not at all concerned that the NHS can track them during a pandemic after all Google and FB track them all day.
If it's opt-in, masses of people will be too lazy, won't care, will forget, will have 'good intentions' but won't use it, will let their battery die, forget their phone.
At least with a 'face mask' policy, it becomes apparently clear that someone is 'not wearing a mask if they are supposed to'.
With contact tracing ... there's no way to flag people.
Without extended contact tracing and 'almost everyone on board' it's simply too dangerous for people to be out and about.
People are going to have to use it to go outside, it's as simple as that.
