I've read most of the comments from Nost, and while they don't claim to wrongdoing (which is probably from advice from lawyers - when you're facing a lawsuit, you don't admit to anything in public), their actions and lack of any kind of claims legally to do what they were doing is pretty evident that what THEY think is pretty different from what the kiddies here are claiming. Nost states that as soon as Blizzard said "take it down" they did - which is admission in itself they knew what they were doing was not legal. All of the logic twisting and claims of rights and such have happened HERE. Nost's approach was to talk to Blizzard, show them what they did, and see if it could help Blizzard clear a path to launch legacy servers as an official project. They don't claim any rights, any moral or ethical high ground, they don't shame blizzard, they even state that they won't be hiding servers in other countries because it goes against their principles.
If you take what they've written and posted in public, it's a different story than what's told and bellowed about here. They never claimed any rights. They never challenged the copyright laws, or Blizzard's rights to shut them down. They never claimed immunity because they didn't profit. Wether their donation links were blatant or not is wholly irrelevant, and the whole thing is so played out now, it's useless scraps of arguement like this that the kids here only have left to chew over and over and over. It's pointless and meaningless, it's forum-PvP trying to score "points", after their 'war" has ended and the victors decided.
And, in the bigger picture, their donations and profit, if any, is still not required to sue them for copyright infringement and DMCA violations. So they played coy with donations - it changes nothing. If this reached a courtroom, it would barely be worth mentioning, unless Blizzard used the total donations over time to calculate damages, if they decided to go for unjust enrichment on Nost's part.
As far as this thread goes, this bickering over their donations is about as meaningful and constructive as the rest of the myths and fairy tales and urban legends that the kiddies here obesess and get belligerent over.
