My first smartphone of any sort was a company issued iPhone 4. I remember that the first version of iOS I couldn't install was chock full of important security patches. I had a 1st Gen iPad, same situation. Apple only updates the latest version of iOS, and everyone else can go fuck themselves. [profanity added to imply honesty and sincerity]
Not that they bear the burden of that $12b. We get to do that for them (where do you think those ATM fees came from?), plus a little extra, because banks treat us like shit and there's nothing we can do about it. They inflate their costs and pass them directly onto us - so saving money might actually lower profits. If something cost them $12b, they were probably charging us $13b for it.
What does it mean? Apple left users without security updates to a device that contains the keys to a user's life for four years before informing them they needed to replace it. If you can't afford to replace your phone every other year, Apple is going to give you the finger and leave you vulnerable.
That is some piss-poor behavior.
Now that you know I'm being honest, we're talking about a phone company that doesn't even know it's own phone numbers. I can't tell you how many times their business support people have transferred me to non-existent internal phone lines, leaving me to call back and go through it all again.
I usually hit the entrance(s) to the nest with wasp killer (usually dusk, dawn is too early), give it a day or so to work, and then jam a garden hose in the hole and turn on the faucet for a bit. Fuck those things.
