Hi Stephen,
thank you for sharing this! I do like the position so far and do agree that this, well, let's call it half-baked court decision causes a lot of problems without actually solving the issue at hand (data protection, right to privacy) and I therefore welcome the WMF being active here.
Just one thing that is important to me: Since the General Data Protection Directive is currently in the making in the EU, Google is trying to use this terrible court decision as a lobbying tool to remove other unwelcome passages in the legislation. We must be careful not become a pawn in between Google's interests and the data protection advocates.
Both freedom of knowledge and right to privacy are legitimate demands. I believe we should stand up against the court decision and its implementation, not necessary the principle, since even we at Wikipedia do permanently delete some information we consider too personal. The incomprehensible thing here is that the de-indexed data is perfectly legal and remains published, but has to be legally de-indexed.
Just to clarify, I don't think this has happened, I simply want to warn of such a risk. I think WMF Legal is doing a great job on this so far.
