In the ethics department I enjoyed "The Cambridge Handbook of Information and Computer Ethics" (978-0521888981). We read part of it for a ethics lecture during my M.Sc., and like most ethics/philosophy piece I found a lot of things to think about.
IIRC chapters are contributed by different authors, so it's not a single point of view (even though of course there is some filtering by the editor).
Since it's from 2010 it is light on more recent developments like AI, however (unlike software) it's rare for ethic ideas to become outdated. So I would not dismiss it due to age. Also it's 5$ used on Amazon, so depending on your situation it's not a huge deal to get it and skim it - IMHO this kind of work doesn't have to be read front to back, instead it's great to get back to it when you feel like and think about a few pages and explore new ideas, re-evaluate your own concepts, etc.
Description from the publisher: "The Cambridge Handbook of Information and Computer Ethics, first published in 2010, provides an ambitious and authoritative introduction to the field, with discussions of a range of topics including privacy, ownership, freedom of speech, responsibility, technological determinism, the digital divide, and online pornography."
Editorial reviews stolen from Amazon:
"...This five-part work examines difficulties in the field of information ethics and offers practical applications and criticisms... Recommended..."
--B. G. Turner, Faulkner University, CHOICE
"...This is a rich and fascinating book, bringing to interpretative debates much that has been hitherto unknown. The chapters are long and complex, and the argument is multidimensional and far-reaching."
