@Marcus Tibesar -

I believe the policy is to enable a feature if it doesn't change the appearance on front before any user action. You have to set the visibility for each widget for something to happen. I use the "Manual Control for Jetpack" plugin by Mark Jaquith to make sure nothing is enabled by default, but I haven't had any use of it since Jetpack changed their policy. The current policy of Jetpack is ok with me.
