On September 1st the European Commission is going to vote a revised version of the European Patentability rules. The proposed revision contains a set of serious challenges to Open Source development since regulation regarding software patents will be broadly extended and might forbid independent development of innovative (Open Source and not) software-based solutions.
The European Open Source community is very concerned about the upcoming new regulation and has organized a demo protest for August 27, asking Open Source supporting sites to change their home pages to let everyone know what is going on at the European Parliament. The Apache Software Foundation has decided to support this initiative, and this is why you are seeing this page.
