Opt-in by default is the wrong decision because it takes advantage of users who do not realize that it is happening.

Out-out by default is also the wrong decision, because most people would never opt in or out and thus is unworkable for Automattic.

What Automattic should to is force users to make a explicit choice to opt-in or out the next time they access their admin console, defaulting to out until they do. They could also email everyone asking them to sign-in so they could explicitly indicate their choice.

They should also show the user exactly how to change that setting in the future just the way they show users how to use WordPress when on-boarding.

Frankly, while I am particularly allergic to false binaries, I cannot think of any other approach that would be correct. #jmtcw #fwiw
