My cynicism fails me on this matter... do I cynically believe that these companies keep deliberately and routinely re- or un-checking these checkboxes because of the obvious benefits of "whoopsie guess you allowed these after all"? Or do I cynically believe that they are just so completely incompetent and inept at the simple act of maintaining settings that there may be a number of these that are not entirely intentional? As evidenced by the number of other bugs and configuration failures and random settings changes on update I see in other places? Sure, these sorts of settings sure seem to get spontaneously flipped more often than the other ones but they aren't the only settings I've seen get nuked on updates.

Now, obviously, considered as a whole, I think we're looking at "both". But when I wonder about specific cases like this one, that doesn't help.
