I already suggested it be a $1 app to add the UI for the feature to switch. That'll keep out the young kids.
do you also advocate vehicles have dealer locked hoods that only they can open?
I know car metaphors are de-rigour here, but that's really not a good metaphor. This is approvals of add-ons and consumables, not repairs. And there are a few other examples. Games consoles, printers, razors.
The bizarre thing is it's framed as if it's imposed on consumers. But of course it isn't. It's entirely opt-in. There's a large number of people that are willing to pay a bit extra for the safety and quality that the iPhone platform gives. And one of the important mechanisms by which that safety and quality is delivered is by controlling what can be installed.
People aren't being MADE to be safer. They CHOOSE to pay extra for the service of being made safer.
Meanwhile, these 35 year old kids are using the PC or Mac computers without such restrictions.... Why is the phone or tablet sacrosanct?
If a phone ever needs the kind of maintenance a PC or Mac needs it's a failed phone. Consumers these days have got something that for most of their casual uses is better than a PC. That's progress.
Sure, there's a need for an industrial grade computing device too, for a start to develop the apps on the more casual devices.
But to make modern consumer computing devices with as troublesome a set of ideas as a PC would be silly. Consumers need reliable appliances, not unreliable boxes of bits that continually degrade and require maintenance.
