Software licensing is a relatively young legal discipline ...
Hmm, I remember talking in the cafeteria of my work about the SCO versus IBM, BSD and everyone else lawsuit 25 years ago. The nice thing about the cafeteria of my work was that most of the year, we can sit outdoors to eat. Back then, software licensing law was already a well established and understood discipline. To claiming that it is "young" is nonsense.
Rather, the question is whether the representations contained in the license, once voluntarily adopted and distributed with a consumer product, acquire legal significance under other bodies of law.
Law does not exist in a vacuum. Law exists for a purpose. Imagine you were right, and all non-GPL open source software had the viral "must release my modification to the source code if I use it in a shipping product" that you so desire. What would happen? Sony would stop selling its product in Brasil. As would lots of other companies. Or Sony would stop using BSD, as would lots of other companies.
This is not what the Brazilian legislators intended. It is also not beneficial to anyone. That alone is enough for you to ultimate lose your case: if the letter of the law, when (mis-) applied, via applying the law in an area where it was not intended to be applied, gives undesirable results, then the law is invalidated, usually by a high court (or constitutional court). If you have hundred of thousands of $ (or a few million Reals), you can fight this fight all the way to the Brazilian Supreme Court, and lose there. There is a lot more fun things you can do with your money.
Why do you not share the full paper trail of your crusade here?
While I completely agree with your observation, and would love to see it all posted in public, let me give you a word of warning: Much of it is in Portuguese. And machine translation of legal documents across languages is very unreliable. In particular since much of the writing will rely on unspoken assumptions, and on laws and precedent-setting court decisions, which also would need to be translated and understood. I speak Portuguese reasonable well (fluently for things like grocery shopping and restaurants) and am a Brazilian citizen, but my first court case in Brazil was very stressful, because I needed to re-learn all the legal language and way of thinking in a different language and different legal system.
So don't put too much hope into actually understanding the documents that are in Portuguese.
Because this shall violate the rules of this forum,
bvdw78. I had a post on a petition deleted.
You don't have to post them here on this forum. It's trivial to find a free web hosting service, and post them there. You can also just upload them to a random storage service (I like Google Drive) and post links to there. If you wanted to share the documents, it would be easy.
I've yawned countless times reading the responses in here. This is tiresome.
I agree, but from the opposite side: You quixotic mission is tiresome and misguided. But it's a free country, do as you wish.
