What were the actual survey questions asked? This sort of thing is very sensitive to how you phrase the question.
The problem with tracking quickly becomes apparent when you're on the wrong side of the fence. If a person honestly believe that it would be okay to track their partner, but not vice-versa that person is an asshole.
If I'm meeting up with him, he'll send me his location on when he's being super lazy just put on his tracker to make him easier to find. Sometimes .. he leaves it on forgetting to switch it off and I tell him to as it'll drain his battery. When you have trust, stuff like this doesn't come up in conversation at all. It's more of a 'what's mine is yours and do whatever...' BUT yes, tracking someone WITHOUT their consent, completely different story ... that's NOT right. Defo needs to be rephrased.
