Why we are fond of the "Linux" philosophy.
Linux respects its users. It doesn't spy on you, it doesn't show ads and it doesn't send data anywhere without asking. This can be verified at any time, since Linux is open source.
Linux is a solid base for any project. It's build in a modular fashion and can thus be economically adapted to any requirement.
Linux and most of its software base doesn't cost you anything. This won't just save you money, but time as well. Time that you would have spent on managing your expenses.
