- "Tudo is distributed with complete sourcecode, which is licensed as GPL."
- "You can always view, edit and upgrade the code."
- "For the software itself and all it's components (operatingsystem,
databasesize etc.), there will be no royalties."
So far so good.
- "For the software-package we charge you EUR 99,50"
This means only that to get the GPL'ed software you can't download it for free, but will have to buy a software package that will give you...
- "You only pay for the service for installion, support and programming."
Doesn't seem like a violation.
Selling Free Software Can Be OK! http://www.gnu.org/philosophy/selling.html
In the GPL FAQ, starting at
http://www.gnu.org/licenses/gpl-faq.html#DoesTheGPLAllowMoney
you can read:
Does the GPL allow me to sell copies of the program for money? Yes, the GPL allows everyone to do this. The right to sell copies is part of the definition of free software. Except in one special situation, there is no limit on what price you can charge. (The one exception is the required written offer to provide source code that must accompany binary-only release.)
Does the GPL allow me to charge a fee for downloading the program from my site? Yes. You can charge any fee you wish for distributing a copy of the program. If you distribute binaries by download, you must provide "equivalent access" to download the source--therefore, the fee to download source may not be greater than the fee to download the binary.
