The text of the declaration would not make sense. They want to extend Directive 2006/24/EC to search engines. But if you read the text of that Directive (http://eur-lex.europa.eu/LexUriServ/LexUriServ.do?uri=CELEX:32006L0024:EN:HTML) it is absolutely unclear how this could help their cause, as the directive only requires the retention of dates, times, telephone numbers, other identification items. And Article 5 (2) clearly says "No data revealing the content of the communication may be retained pursuant to this Directive."

So under the proposal of the Declaration they would get the times I accessed Google & Co. Big deal. This is how serious this declaration is.

So far the European Parliament has been relatively good at handling issues of freedom and civil liberties (this is why the national governments quickly passed the SWIFT agreement with the US before the new Lisbon treaty came into force which would have required the approval of the European Parliament). Therefore I trust them (for now) that they would not change the meaning of Art. 5 (2) of the aforementioned directive.

In Brussels, Belgium, the local public transportation company STIB/MIVB used to not like links to their site either: Until about a year ago when you visited their website, you were greated with a popup, which told you that you may not link to their pages without their explicit consent. Only when you accepted this, were you allowed to use the website... I don't know why a service provider such as a public transportation company would ever want to be not linked to...
