Recently, IONOS and Nextcloud announced their new, sovereign office suite called “Euro-Office” and claimed they were using components of ONLYOFFICE. It seems they are doing so without checking the licences first and without cooperating with them.
Original announcement:
Nextcloud and Ionos are promising a modern, open-source office suite for the summer. To achieve this goal, they have forked OnlyOffice.
ONLYOFFICE reply:
Based on publicly available information, the “Euro-Office” project uses technology derived from ONLYOFFICE editors in violation of our licensing terms and of international intellectual property law.
Weil you can (because you still own the copyright after giving your work that license), but you have given a legally binding promise to not impose additional restrictions so it won’t do you any good to try
OK this is getting a bit hairy, but AFAIK only the creator of the GPL code maintains copyright, and can take his code to a closed source project.
BUT the code that has been released as GPL remains open source, and cannot be made to be NOT open source.
So anybody has a right to use it, as long as they keep it open source. So in the case of open source projects, it’s academic that the creator of the code maintain the right to use it without the GPL conditions.
Yes, a creator can create a closed source copy (independent of the GPL’d work), assuming they have full ownership or permission from all contributors
You are mixing things up, I’m not talking about the project, I was exclusively talking about the code someone had made personally.
Linux for instance can never be made proprietary, because it’s impossible to get permission from all developers.
But anyone who has contributed a piece of code, can use that piece in other projects under different licenses.
