Without having read each and every line of the uela, a few points:
- There is an official blue thread on the official European wow forum that is asking the community to list all mirror sites where the patch can be downloaded. So I question that 'distribution' of the patch outside the wow client is illegal cq immoral.
- Paying someone for the distribution of software seems to be illegal in my book.
- Providing someone with the tools to make you a copy is not illegal in my book (i.e. send him the usb stick / dvd with enough stamps included).
- Covering the expenses for the tools to make you a copy ain't illegal either in my book (i.e. you pay him the price of a usb stick + the stamps).
- Paying/tip someone for the effort to make you a copy (i.e. walk to the post office, inserting the dvd, click copy, etc) seems to be illegal in my book.
Pretty weird maybe,
but imo you can cover someones costs, but can't pay for his effort. That aside, I think you have a genuine case, and if you can't order the patch on DVD directly from blizzard, I think there is little problem to do it this way.
My 2 cents.
