The title implies that losing this lawsuit is threatening the existence of the Internet Archive. Is that really the case? If it is true, then maybe IA should be run by somebody with better judgement. This was a project with a massive chance of failure (how could anyone think that this wasn't just blatantly infringing?) and a low payoff. If it's also an existential risk, then wtf are they doing running it?
It's not a game. It's resistance by every mean available against corporations that want control over what knowledge we have access to. He did an unexpected and courageous move for the benefit of humanity. The Internet Archive is a huge responsibility because if not exhaustive, it could falsify history. It's leaders mandate is to preserve history, not to preserve what they let him preserve
The IA resisted nothing, achieved nothing, made nobody's life better, and created an opportunity for bad precedent.
It was an utterly boneheaded move. (It has also nothing to do with "exhaustive preservation")
