I don't think anyone was arguing that they want to "simply" keep owners out, just because they can or they're bad, bad people. Remember how I said "most people would agree that they have readily explainable motives for" keeping owners out? Some of those motives are "total control of both the screws and bits end to end" and "no chance of someone causing damage by using a wrong size bit". The reason why people are complaining about this is not because they think Apple has no reasons for this, but because they think Apple's reasons are wrong, as in (for example) "it's my device, I paid for it, so I should be able to change the battery and if I damage it, it's my fault." Of course, other people are free to disagree. I'm not arguing that, either ;)
