Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

LibreOffice

  • Real-time collaborative editing is far behind Microsoft 365 and Google Workspace, and for teams who co-edit this alone usually decides the question
  • Mobile support is weak, which is disqualifying for a workforce that reviews documents on phones
  • Complex Microsoft Office documents still lose formatting in transit, so exchange-heavy workflows need testing with real files
  • Central policy management, conditional access and audit tooling are thin against the commercial suites
  • Advanced spreadsheet work is where the gap with Excel is widest, and it affects exactly the users least willing to change

ProtonVPN

  • Free plan limited to one device at a time
  • Free plan restricted to 10 countries with random selection
  • Pricing amounts not clearly published; shown as variable

Answered from the vendors’ own pages

LibreOffice: Is LibreOffice really free for business use?

Yes. It is open source with no per-seat licence and no restriction on commercial use. The Document Foundation is funded by donations and sponsors.

LibreOffice: Does it have AI features?

No. The 26.8 release states it contains no generative AI, that documents are not transmitted to remote services, and that no component requires network access.

LibreOffice: Can it open Microsoft Office files?

Yes, and save back to them. Round-tripping complex documents is imperfect between any two suites, so test with your own files before committing to an exchange-heavy workflow.

LibreOffice: Why do governments use it?

Two reasons: no per-seat cost at scale, and OpenDocument is an ISO standard implemented by more than one vendor, which matters for archives that must stay readable after a vendor relationship ends.

LibreOffice: What is the biggest reason not to use it?

Collaborative editing. If several people work on the same document simultaneously, Microsoft 365 and Google Workspace are substantially better and that gap is not closing.
