I would want the CEO to:

1) Immediately delete all of the non-user data

2) Send an apology e-mail to each Path user explaining the situation

3) Write, by hand, a corresponding apology letter for each Path user

4) Hold a townhall-style meeting in which members of the public can ask him questions

5) Pay, out of pocket, the travel expenses of anyone who attends the townhall meeting

6) Wear an indicator of shame (large necklace or a sign) for as long as he is CEO of the company
