Because productivity shouldn't come with pop-ups.
If you are a home user, a student, or a tinkerer who is tired of ads interrupting your flow?
On paper, WPS is the golden child. It’s lightning fast, has near-perfect compatibility with .docx files, and that "Tabbed View" (tabs for multiple documents in one window) is a feature Microsoft should have stolen years ago.
Sometimes. If you download a repack from "HackTools69.exe" on a random Russian forum, you deserve the crypto-miner you get. However, trusted repackers (like the ones from Ru-Board or specific "Silent" installer communities) are often vetted by thousands of users. They usually strip out the telemetry and the malware.
Legally? No. You are circumventing the licensing model. Practically? WPS Office is a Chinese company that largely looks the other way regarding repacks because it drives market share away from Microsoft. But you are technically using a "cracked" product. The Verdict: Should you do it? If you are a corporate user handling sensitive client data? No. Stick to the official version or pay for the license (it’s only ~$30/year, which is a steal compared to Microsoft 365).
