Opt-In??

Often when you go to order something online, just before you click on "Order" there are some boxes along the lines of "Please add me to your mailing list" and "Please send me information on more products I might like."  These boxes can be opt-in (not pre-checked) or opt-out (pre-checked).  One of my pet peeves is when I notice the Opt-Out box just after I click 'Send'.  What does this have to do with anything?  Read here - http://www.infosecisland.com/blogview/23414-Why-iOS7s-AirDrop-Is-Risky-for-Business.html to learn about some of the risks of using AirDrop.  In a nutshell, what if comes down to is one has to 'Opt Out' to keep files safe on mobile devices.  When we get a new phone, tablet, etc, how many of us actually spend a lot of time to consider how secure our information is?  Would it be smarter to have all of the neat 'convenience' options be opt in, so that people aren't less secure than they think?
