Which is neither here nor there. Parent doesn't mean a smartphone doesn't have the cpu power etc. of being a general purpose computing, he says it is not one.
People were justifying locked down smartphones by saying they're not GP computers.
Factually, if they were open, they could be GP computers. The only reason they aren't is because they are locked in the first place! That justification for locking phones is based on a consequence of them being locked, so it doesn't make sense.
That's the difference it makes.
"It's not a computer" by that I mean "I don't want it to be a computer" in the sense that if it had the complexity/risk of a PC I wouldn't buy it in the first place.
That Apple and Google have taken that from the user is unfortunate and I think there's not much of a case to be made against that. All you've been saying so far boils down to: you don't want an open phone, and because Apple and Google have coincidentally made the same choice for their customers this kind of paternalism is fine by you. Kind of a short sighted position, no?
