I wasn't doing it to avoid phone-homeage, since I have a legit copy - simply because the launcher is a huge, unnecessary mess and I don't want to see it.
I have a legit copy as well, so this phoning home thing isn't just symptomatic of arr'd copies. As Pescado just said, phoning home is bad so you might consider turning off your internet connection while playing the game or getting something like Little Snitch to protect yourself during general internet tomfoolery.
