Has anyone tried to ignore iOS updates recently?
These are product updates and often times contain security and stability fixes, nobody is trying to trick you here. Apple is proactively trying to keep their users up to date, I see no problems with this.
Edit: Take a look at how any Stable/LTS Linux disto handles this. If a bunch of hackers can do it on such a diverse software stack, surely the company with the largest cash reserves in the world can figure out how to do it on a software/hardware stack they control completely.
