It makes a lot of sense for Germany to keep some independance from foreign proprietary cloud providers (Microsoft, Google); Money very well invested imo. It helps the local industry and data stays under German sovereignity.

I find your "open-source-washed" remark deplaced and quite deragoraty. Nextcloud is, imo, totally right to (try to) monetize. They have to, they must further improve the technical backbone to stay competitive with the big boys.
