Ask HN: Is Nextcloud a Great Alternative to Dropbox/Google Drive for Startups?

I was wondering how easy and reliable it is to work with NextCloud in any professional setting. Does it put too much maintenance work on DevOps to a level that makes just using things like dropbox the standard way? I read that German government uses nextcloud because it offers better control over data. Do the companies care about this matter too? or should I just learn big cloud alternatives?
