Why would I want to pay for a service that Google and Microsoft give me for free?
If something does not cost money, it does not mean it’s free. The infrastructure and the people working on it need to be paid. Companies that give you services for free make their money in other ways. Most of the time, this is by using your data which is stored in their service. They analyse your information, profile you and sell this information to other companies. These will mostly use it for targeting you with ads. We think this is a bad thing. We would rather tell you how much it costs to host a service like this, so you can decide if you want to share your data, or pay a couple of euros per month to someone who guarantees they will never spy on you.
