@simontatham ip annoyed me most by being two letters that don't really make sense when referring to a network interface, it seems semantically worse. I don't know enough about why it was changed to decide if I feel it was necessary but I think changes that touch a lot of existing scripts are a bit rude. Such a change feels like a challenge to the idea of composition of small programs to get things done, which in turn feels like a threat to using the computer in the way that you want - but only for people who do that. Sometimes I think people read Who Moved My Cheese? and then decide to move the cheese for their own reasons. A horrible act of bullying disguised as necessary change or a byproduct of progress and improvement, sometimes it's impossible to tell.
