A better analogy would be Lenovo, Dell, HP requiring all software installed on their laptop or desktop machines to be purchased through them and skimming 30%.
If they can add value then they would be able to do that.
According to whose definition of value?
Their view of "adding value" may be my (and my customer's) view of "imposing".
I didn't imply a positive or negative view (though I do disagree with it). I was simply offering a better hardware analogy since I disagree that Apple's hardware lock-in would be similar a Microsoft Windows lock-in.
