In the long contest between open and closed systems, LibreOffice has once again raised its voice against Microsoft, arguing that the dominance of proprietary Office file formats is not merely a market outcome but a deliberate architecture of dependency. The accusation — that switching costs are engineered rather than incidental — touches on one of the oldest tensions in the digital age: who ultimately controls the tools we use to work, and at what price. The dispute, unresolved for years, grows more consequential as organizations weigh the economics of licensing against the friction of escape.

Consumers may face higher switching costs and reduced flexibility in choosing productivity software. Users invested in Microsoft Office formats face barriers to adopting alternatives like LibreOffice, potentially limiting competition-driven price reductions and innovation.
This renews antitrust scrutiny of Microsoft's market practices, particularly regarding file format standards and interoperability. Regulators (EU, US DOJ) may consider enforcing open standards requirements or mandating format compatibility to promote fair competition.
