Yeah, annoying. My guess is that it's to prevent updates like timezone data
changes from getting counted as security bug fixes in statistics made by
clueless analyst report firms.

Yes, thank goodness. Updates are essential. There's two cases: informed,
active sysadmin; vs. not paying attention.

With updates off by default, the informed sysadmin may or may not turn them
on -- but they're the case which is most likely to apply security updates
quickly when needed. The other case ends up with no updates. This issue
affects the rest of us in the form of botnets and spam.

Updates automatically = if you don't like it, you can turn 'em off. If you
don't care, you've got a minimal level of protection.

I think you'll find the current popular fanboy "ooh I'm going to leave
threat distribution to be Ubuntu". Two years ago, Gentoo, but apparently
that's passé now.
