I read the page, and I'm still not clear what they want me to do. Do they want me to buy something from one of their partners? If so, what do they want me to buy, and why is it better (either for me or the developers) than just using the free LibreOffice? I actually _do_ need a document and spreadsheet suite which works on Linux, and I would pay for one which works well. At the moment I kind of get by between Google Docs (generally reliable, functionality often not quite there) and LibreOffice (lots of functionality, UI feels clunky, sometimes crashes). If LibreOffice are offering me something that makes my life better, I will likely buy it.
