I don't think so. The company I work for is really focused on digital independence. Their core business is industrial electronic component design. The whole supporting office runs on libreoffice, thunderbird, mattermost and nextcloud, all hosted on company premise. They employ two full-time admins, one for the windows clients, the other one for the linux clients (which one can ask for) and servers. This whole setup is, according to them, surprisingly easy to manage and maintain, you just have to find a boss who's willing to try it. Maybe it's different when you're a software shop and really need s3 or something
