> Now there's the obvious argument that people should have the freedom to control all their computing devices, but that freedom comes at a cost, which is that freer devices are, I would suggest, harder to maintain.(i.e. you need to understand more about the operation of the device in order to manage it). If you're a technical person, you may not see this as a problem, but remember mass-market consumers aren't necessarily very technical...

That's a common fallacy perpetuated by Apple and similar companies but it's simply not true. Having the ability to unlock your device, install apps after you enable unknown sources and hange other parts of it do not have to come at the cost for "average user" (whoever that is). You can make a secure simple default and still not waste development time and resources locking down the devices.
