I question the 'expertise' of a random poster on the internet and the reasons they would go to such lengths (astroturfing does happen, especially with powerful lobbyists in play). I'm no lawyer but just glancing at their 'analysis' I spotted something which suggests they have little knowledge of EU law and practices, or simply chose to ignore it. They try and defend Article 11 with

>Aha. If an ISP only keeps IP logs for a month, or doesn't do so at all, then the copyright holder is without any recourse. You can't hand over information you don't have.

and again

>whilst ISPs may be ordered to hand over information on infringers, there is nothing requiring them to gather information to do so, and there is a specific clause

I guess they don't know about the Data Retention Directive (2006) then. Where I live in the EU ISPs keep data for the max 2 years.
