I am, by far, not a Microsoft fan.
This is one of those cases where in a good and honest legal sense the complainant does not have a very good case, and I don't believe any but a very activist court would disagree.
On non-legal, philosophical grounds however, you would think that if you say you are doing something for purely altruistic reasons, then wouldn't the people you claim to be helping be more involved in the process, than it seems Microsoft permitted.
Many a charitble project has gone badly astray because of the arrogance of those running the project.
You would think that would not be the case if the indigenous group in Chile had been brought into participation on the project, in the first place, no matter the final product.
I hate Windows with a passion, but Microsoft is in the right on this case.
