Is it really derogatory?

It seems to that the term covers the hardware associated with iOS and doesn't imply anything one way or another about the company which manufactures it.

It is not as if there is just one "iPhone" and one "iPod" and one "iPad". There are diverse models of each and little point in being pedantic over all the retinas and 2' and 3's and 4's and GS's and plain old S's and mini's and nano's when the important point is that one cluster of them is required to use the product.

It succinctly captures the entire category of "small personal electronic device from Apple" including all present and plausible future product lines. Unlike M$, it has both derogatory and non-derogatory intonations and connotations.

iDevice captures the same category without any derogatory intonations.

It's meant to be a pejorative term. Apple is an enemy of our freedom.

The intended contempt may have eluded brudgers, bitwize, and peteretep but it wasn't lost on me - hence my question.

Because it's considerably shorter than "iOS device" and "iPad or iPhone or iPod"?

iPad is shorter still. This app isn't universal.
