The action that path says they've taken - which is to delete all the contacts they have so far collected - serves to move me to forgiving them, 'cos that action is the only thing they have going for the contact collection being a "mistake".
"Privacy empathy" (no .. pun not intended I swear) seems hard to come by these days.
And if you ask me, that breach of their users trust is not something that you can just turn around. If they didn't understand that their users might get upset that only makes it worse (when it comes to trusting them).
