Personally I don't see why anyone on this forum should need to justify their reaons for sharing or not. I know there are are arguments for and against sharing, but at the end of the day, no user is under obligation to share/not share.
Even if you did get "free" network access with a new box, it's not free as it was included as part of the deal when you paid the princely sum for the box, no ??
I bought my box new and thus for my money expected a box with one years access, for which I paid. Thus I don't owe anything more.
Will send you a zip Alex.
