It's always a good thing to have multiple players and I hope we can have actual EU-based alternatives, but I feel like this project, simply being a rebranded NextCloud as far as I can tell, is less interesting than La Suite numérique [1] developed by the French government or CryptPad [2] developed by XWiki, a French company based in Paris.

Cryptpad is great.
