and you can argue this is "fair use" or whatever, not the point now, the point is that it definitely makes those accusations no longer "baseless".

in addition, it is not given freely to the world, it is the knowledge of the Internet/WWW being sold back to you as a subscription service. it's not free. and it's not even "given", because they can (technically) turn off the tap at any moment and you don't have it any more.
