Ditching Microsoft 365: Why Office Software Without AI Might Actually Be Better

When AI Is Everywhere, Some Choose to Escape

As major tech giants race to embed AI assistants into every product, a counter-trend is quietly emerging. Recently, multiple overseas tech bloggers and users have publicly announced that they've replaced Microsoft 365 with the free, open-source LibreOffice — and are "very satisfied" with the switch. The reason is surprising: LibreOffice's lack of a bundled AI assistant has actually become one of its biggest selling points.

Microsoft 365's 'AI Anxiety'

Since Microsoft deeply integrated its Copilot AI assistant across the Office suite, user feedback has been far from universally positive. Many users report that Copilot's frequent prompts and suggestions disrupt their normal writing and editing flow. More critically, Microsoft 365 subscription costs continue to rise, with the personal plan costing around $100 per year and the family plan exceeding $130. For users who only need basic office functions like word processing and spreadsheet editing, paying for an AI assistant they don't want is hard to accept.

Microsoft recently announced plans to embed Copilot even more deeply into Windows and Office applications, accelerating the exodus of users who prioritize privacy and a streamlined experience.

Why Is LibreOffice Winning Over These Users?

LibreOffice is an open-source office suite maintained by The Document Foundation. It includes core components such as Writer (word processing), Calc (spreadsheets), and Impress (presentations), directly comparable to Microsoft Office. Its key advantages can be summarized as follows:

• Completely free: No subscription, no account registration — just download and use
• Offline operation: All document processing is done locally with no internet connection required, fully protecting data privacy
• No bundled AI: No default AI assistant pop-ups or suggestions — a clean, focused interface
• Format compatibility: Supports opening and editing Microsoft Office formats (.docx, .xlsx, .pptx), with native support for Open Document Format (ODF)
• Cross-platform support: Runs on Windows, macOS, and Linux

For everyday tasks like office work, academic writing, and financial reports, LibreOffice is more than capable.

The Deeper Thinking Behind the 'De-AI' Movement

This phenomenon raises a question the entire tech industry should consider: Should users be given full autonomy over whether AI features are enabled?

It's not just Microsoft — Google is also aggressively pushing Gemini AI features in Docs and Sheets, and Adobe's Creative Suite is going all-in on AI as well. These AI capabilities do boost productivity for some users, but the one-size-fits-all, forced-rollout approach has triggered a backlash. Users' core demand is actually quite simple: I need a quiet, efficient tool that doesn't interrupt me — not an agent that constantly tries to 'help' me.

From a product design perspective, AI features should be an "optional enhancement" rather than a "default standard." Using AI as a justification for subscription price hikes is especially likely to breed user resentment.

Limitations and Future of Open-Source Office Software

Of course, LibreOffice is far from perfect. In collaborative editing, cloud storage, and mobile experience, it still lags significantly behind Microsoft 365. For enterprise teams that require real-time multi-user collaboration, fully replacing Microsoft 365 isn't realistic. Additionally, LibreOffice occasionally encounters formatting inconsistencies when handling complex Office documents.

However, for individual users, freelancers, and privacy-conscious groups, LibreOffice offers a choice that is "good enough and free."

Outlook: The 'Right to Choose' Will Become a New Competitive Edge in the AI Era

As AI features continue to permeate software products, whether or not a product includes built-in AI may become a new dimension of product differentiation. In the future, products that respect user choice and offer an "AI off switch" may actually win a loyal user base. Technological progress should not come at the cost of user autonomy — and that may be the most important lesson LibreOffice's unexpected rise has for the industry.
