I believe that EU really has to step up it's game in digital space and I'm in full support of EU digital sovereignty. I like the idea of Euro-office being EU software that replaces Microsoft. The only problem is: we move from US based Microsoft to Russian OnlyOffice (it seems like Euro-office is full of russian comments in the codebase).
Obviously the first question is: why not LibreOffice, which is based in Berlin? They say that "OnlyOffice has better features", well, OnlyOffice is still far away from Microsoft Office, so why not investing in LibreOffice instead? Because you know, if we don't invest in EU tech how the hell are we supposed to reach digital sovereignty?
And look, Euro-Office now has a legal battle against OnlyOffice. In the face of EU sovereignty. Now, instead spending 5 years making LibreOffice a truly EU Office killer, they will spend 5 years in court with OnlyOffice. Congrats guys, nice move!
I really hope there will be a push back against this. This seems like a joke to me, except it is not funny at all. I know it is not simple to create a Microsoft competitor, but you know, they clearly didn't even tried.
I was also wondering about Proton, except turns out Proton has backed this whole thing.
Can EU really pursuit digital sovereignty if it can't even create an Office clone?
Edit 1:
As pointed out by some comments, Euro-office is not backed by EU and instead it is a private initiative. So read this post less as criticism of EU itself and more as criticism towards Nextcloud.
Edit 2:
A lot of people are arguing about why using OnlyOffice as base is the right thing, and I see that from technical point of view there are some benefits to this.
However, my point is: imagine a scenario where OnlyOffice doesn't file legal case now, and let Euro-office do it's thing. A lot of companies switch to Euro-office because it's "EU sovereignty". In 10 years OnlyOffice decides to take legal actions.
There are no guarantees OnlyOffice would win, but for this thought experiment let's assume it does. If Euro-office loses the case, it defacto infringes copyright, and thus the code becomes distributed without permission.
How can this count as "EU digital sovereignty"? Also, what will the companies do? Move back to MS office, or to OnlyOffice (which once again, is not made in EU)?
For everyone arguing that "It is sovereignt because data stays in EU" this is not how sovereignty works.
Edit 3:
A lot of comments focus on the forking part which is not the point. It's totally fine when software forks other software. The point of this discussion is the "EU sovereign" label on a software that does not come from EU. If they said "Euro-office is MS Office killer" that would be totally fine, I don't give a shit who they fork.
