I personally wouldnt pay, but your statement is a bit lacking. Going to make some assumptions... First you entered on a site that offered OpenOffice and sevral other pieces of software for download. In order to download, you had to enter our personal information and agree to something thus entering into an agreement. In that agreement you subscribed to my download site which offers high bandwidth downloads of popular (free/shareware) software. The agreement isn't for the software, but for use ofmy server. For that server i have every legal right to charge you money. Problem is this case is, prove that the info that was entered, was indeed entered by that person. That said person was over 18 years of age. And that she entered that agreement willingly.

You dont give enough information. Although it is legal to sell openoffice (you charge for packaging a hardcopy, or download), it doesnt mean that the way it is sold constitutes a valid sale. Further more, there are some european limitations on consumer sales over distance (be it by phone or internet). As a consumer you have some time to reconsider. It greatly depends on what was being sold, and how they did it. If it was unclear that you were buying something, chances are that a court would rule the agreement void. The law favores consumers over companies, since companies a supposed to know what they are doing.

You make a strange assumption. You state that the limiting factor is space, but yet assume they bill for weight. For normal freight the space is the dominant factor, to ship a single container from us to eu cost about $2700. The container may contain about 22000kg say 48000lbs. doesnt change the fact that shipping still costs far less then the energy saved. Of course you could do a much more elaborate analysis. Although incandescent lights do generate less light per watt, doesnt mean that the rest of the energy is wasted. The energy not used for light is converted in heat. Which means you have to use less energy for heating.
