But Apple doesn't just push security updates. They have a well established track record of pushing entire new OSes the same way, a very poor record of crippling performance or outright bricking older ("old" is hardly a fair description) devices in the process, and a stubborn insistence that applying these updates is a one-way process that may never be reverted regardless of any harm they do. Any business that adopts such customer-hostile policies deserves every bit of resistance they bring upon themselves, and I have not the slightest sympathy for them.
