open and accessible != free from copyright

As per court ruling, training is fine when they have lawful access.

i.e. open and accessible on the general web is fair game, torrents from the pirate bay is not.

Feel free to argue that copyright law should be changed; this wouldn't be the first time it needed a significant update because new technology made it cheap to do at industrial scale something that was previously so hard that even being able to pull it off made you look legit.
