Why software must be free

Most people agree that software vendor lock-in is a serious problem and Free Software a solution. The controversial question is how realistic this solution is.

On this page we try to explain why we believe it to be realistic. You don’t need to believe in our vision as much as we do, you may use our software and our services even if you are skeptical.

Our customers are free to choose another service provider at any moment without loosing the product that has grown by our collaboration. This is our warranty to a relationship that fosters long-lasting satisfaction for both you and us.

So what?

An understandable and often-heard reaction is to say „So what? For me as a non-expert, software products like MS Windows, MS Office and Google Maps are easier and cheaper to use than Linux, LibreOffice and OpenStreetMap“.

Yes, it’s easier, and sometimes cheaper. Using free instead of proprietary software is like living in your own house instead of living in a rented one. It has advantages and disadvantages. As a house owner you have more rights, but you also have more responsibilities.

The question is whether you care about your independence or not. Using proprietary software makes you depend on its vendor. If you have no problem with depending on giants like Microsoft or Google, then feel free to stop reading this page. God bless you.

Why software should be free

There are a few aspects of software business you might care about even if you are not an IT expert:

  • As an end user you actually are an important contributor in the software development process. When you have a problem with a software product, then its owners should be thankful that you take the time of explaining them your problem. Every support request increases the value of their product. Most business models make you pay for getting support although in a certain way it should be the opposite.

  • Using a software product makes you depend on its owner. The owner decides which features to include or remove in new versions, and which versions they continue to maintain. The owner decides about the price to pay. The owner has motivation to bind you to their product.

Sustainably Free Software

Our software is more than just „free“ or „open-source“: we call it sustainably free. That’s actually a neologism. It means that we develop and maintain it using a business model that is based on sharing rather than limiting (reserving) the right to use it.

While Free Software becomes more and more popular, it gets increasingly misused by players who still rely on some proprietary part for generating revenue.

  • They gain control over the usage rights on some part of the product like an installer or a front end.

  • They use a liberal free license, which leaves them the legal back door of switching to a proprietary license when the product has acquired enough popularity.

When such attempts are disclosed, they lead to a free (but weakened) fork in the best case, or to the death of the product in the worst case.

A legally free software product may become non-free when one of its components is non-free. Documentation is an important part of a software product. An otherwise free product is not sustainable when documentation and expert knowledge about it is controlled by a single entity.


This page explains why we are proud to say that Synodal Software is not just „free“ but sustainably free.

Synodal Software can be used by anybody and forever to write a new application or host an existing one. You can do the work yourself or delegate it to a service provider of your choice.
