I'm going to take a slightly more nuanced take on this as someone who works in the enterprise software ecosystem.

Microsoft doesn't just sell office to the government or university anymore. Their Microsoft 365 subscriptions include e-mail, office, intranets, communications, security, collaboration tools, and even more.

You can replace the office part with Libre Office no issues, and for home use I would absolutely recommend that instead of paying for a Microsoft license, but the moment you need to start building your own e-mail servers, file sharing systems, getting software for messaging and video calls, etc. the price (software, hardware, maintenance, tech support) goes up to well above what Microsoft charges.

Unfortunately, Microsoft provides decent value.

I'd love to see a non-American competitor that offers such a comprehensive business package, but there isn't even a realistic American competitor at this point, Google is the closest with Google Docs/Sheets, Gmail, Google Meet, Google Drive but having used it extensively it's still falls short of what Microsoft is doing and of course it's also American.

If you need to sign up to 6 different companies to get the same functionality coverage it's never going to be as integrated, as easy to use, or as cheap.
