All of which would be fine for people who want this, but the issue is there is no option on many computers. For users who don't want this functionality, who don't enjoy their computer doing shit in the background when not using it, there is no option to disable it fully. It's either shit it down or accept this crap as a consequence of sleeping it.

Also, when laptops are in bags, ventilation isn't very good. I'd rather it not be trying to do anything in there, at all, whatsoever, except staying asleep.

But more to the point

So if a laptop sitting in a bag can wake up, sync all your emails and do all your patches while it's in your house and internet-connected

Another way to frame this is "what if Microsoft could do shit at literally any time and the only way to stop them is to shut down fully or get out of range of any any known wifi network".
