I think the part that people have trouble with is the idea of not having control over their own hardware. Not that I agree with this, but the reasoning is something like: if you buy a physical device, you own it, and should be able to do anything you want with it, including using its full capabilities.
The conflicting moral intuitions here are about ownership of an object vs. payment in exchange for a set of benefits. In terms of the latter, this is clearly a case where everyone wins, but that doesn’t prevent it from seeming “wrong” in terms of the former.
This is really quite similar to the “wrongness” people feel about, say, region-locked DVDs.
