Re: Don't shoot the messenger
You obviously missed the nuance of the ruling. The fact that TPB themselves deliberately and methodically categorize, index and filter records according to context and content of the files being pointed to, knowing full well as to the legal status of said content, tipped them over the edge into the waters of illegality.
From what it seems had they done very little in that regard and simply presented the users with an uncurated list of files it found, then they'd have been fine.
So since Microsoft, Facebook, Google et all do not categorize other people's files, posts, messages etc., especially being aware of the legal or illegal status of said content, in the same way, that legal nuance doesn't apply. Any categorization of posts or files is performed by the poster or other users.
