For the majority of the services C&CZ uses free software and open source software. Therefore, some time ago the idea emerged that the C&CZ employees would vote each year which projects would receive a donation from C&CZ. This year the Mozilla Foundation was chosen. Many people will know the Mozilla Firefox webbrowser and the mailclient Mozilla Thunderbird and maybe use it hours a day. But the Mozilla Foundation does a lot more to try to ensure the internet remains a public resource that is open and accessible to us all.
