You or I might, but companies have a constant flow of new middle management who want to make their KPIs this quarter and will shove their own mother in front of an oncoming train to get there. Corporations don't learn, doubly true for corporations like Apple who have basically captured an audience within their walled garden, the motivation is always all the money now, not some money consistently forever.
Even when you have a company like Samsung with their exploding battery fiasco. Sure they have protections now in place against designing a new product with bad batteries, but give it some time and they'll do it again when a middle manager (who wasn't there the first time) ignores the recommendations of their engineers and the company guidelines so they can save $0.001/phone by using a slightly inferior battery design and net that neat bonus for keeping costs down. It will always happen.
My kids have child phones on Google Fi which allows me to shut down their Internet with a couple of button presses. Are they simple devices if I geofence their internet access off while they're in school? I somehow doubt it, but it does meet the definition as you've stated it, which in turn means it is as @originalucifer said, not exactly cut and dry.
