Non Sequitur
"The Chocolate Factory's new strategy is to make life difficult for the casual user – the hardcore pirate will easily find what they want, and would do so even if Google was 100 per cent free of any links to infringing material. You don't need Google if you know where to go."
Okay, frame of mind set: we're talking about the fact that Google makes it so easy to find stuff that casual users can easily infringe. Finally someone understands that piracy is a multi-faceted industry.
"But allow the hardcore pirates tell the story."
Wait, what? Hardcore pirate are, according to the earlier statement, a different class of user than Google is targeting here. Google can't stop the hardcore pirates; you said so yourself. So why rely on a post from someone you know is beyond the scope of the given changes?
"The relevant results still come up on Google"
Which is consistent with the stated proposals: "...filtering search terms a little, from Autocomplete but not the main search index..."
"The TorrentFreak audience still considers Google a friendly intermediary."
The TorrentFreak audience (generally) falls into the class of hardcore pirates, unless I've missed a trick.
So what you've basically said here is:
1. Google promised to make changes to deter casual piracy but not hardcore piracy.
2. Google has released a status update on those promises.
3. Hardcore piracy has not been deterred.
4. Therefore, Google has not succeeded in their promise (to deter casual piracy.)
