Ain't nobody got bandwidth for that

from here

It's one thing when your computer needs to update, or maybe an app on your phone needs an update, but when your refrigerator and television and light bulbs and toaster and oven and clothes washer&dryer and kettle and water bottle and salt&pepper shakers and toilet and bed and door lock and thermostat and bathroom mirror all need software updates ... that's just way too many things using what precious little bandwidth you have to try and find updates for themselves.

And that's not even counting the possibility of bad updates that brick the device.
