Ubuntu is free and open-source. We will never charge you to install and use Ubuntu, and you can always access, modify, use and distribute our supported applications. In fact, you are encouraged to do so! Not only does this mean that you save money on your software, it also means that the software you use is completely transparent and open to scrutiny. Security problems are found faster, no nasty surprises can be included without your knowledge and you can even make changes to Ubuntu yourself. Freedom!
