My own view is, I thought we were all agreed that the idea that Microsoft can restrict Wine from even using
ideas from Windows, such that people who have read the leaked Windows source cannot contribute to Wine, was a horrible abuse of the legal system that we only went along with under duress? Now when it's our data being used, or more cynically when there's money to be made, suddenly everyone is a copyright maximalist.
No. Reading something, learning from it, then writing something similar, is legal; and more importantly, it is moral. There is no violation here. Copyright holders already have plenty of power; they must not be given the power to restrict the output of your brain forever more for merely having read and learnt. Reading and learning is sacred. Just as importantly, it's the entire damn basis of our profession!
If you do not want people to read and learn from your content, do not put it on the web.
