What’s also alarming, researchers said, is that the hackers have gained access to keys that may allow them to regain entry even after a system is patched.

Once again, a security vulnerability in Microsoft’s software was exploited. And of course: no system is completely secure. But when almost everyone uses the same software, a single flaw becomes a widespread risk. That’s exactly the case with Microsoft Office, SharePoint, or Windows.

That such dominant software poses a security problem is no accident, but a direct consequence of market concentration. A monoculture system is efficient, but fragile. Microsoft’s position in the market is not the result of superior technology, but of decades of dependency.

Digital sovereignty begins with diversity. Anyone who seriously talks about security must also talk about alternatives—and use them. Because only a diverse market truly makes attacks harder.
