I think we might be making different assumptions. There are 3 options as I see it

1) If the contract signed by the patient is silent on the topic, and you have their information, you are free to contact them.

2) If the contract signed by the patient explicitly says you can not contact them for this reason, then I think it clearly unethical to do so.

3) If the contract is ambiguous, or the intent is unclear, then it is a judgement call.

I am talking about #2 and I think you are talking about #1 & 3.

There are valid reasons why people would want to select #2, and if they do, their wishes should be respected.
