In the world of technology, “open source” is often celebrated as a synonym for free. Free to use. Free to share. Free to modify.
But here’s the truth: “open source” does not always mean zero cost—especially in the complex world of software licensing.
What Does “Open Source” Really Mean?
Open-source software is built on code that is publicly available. Anyone can inspect, modify, and often redistribute it. This transparency fuels innovation and collaboration—and has created some of the most powerful technologies in the world.
Examples of open-source software include:
- Linux operating systems
- PostgreSQL databases
- Kubernetes container orchestration tools
But there’s a catch.
The Line Between Open and Owned
Just because software starts open source doesn’t mean all versions of it remain that way. Vendors can—and often do—build on top of open-source foundations and offer commercial versions. These versions may include performance enhancements, technical support, or integration features—and they come with licensing costs.
The line between open source and commercial ownership can be blurry. And that’s where organizations get into trouble.
Case Study: Java
Java is a great example. For years, Java was widely considered a free, open-source programming language—integrated into everything from banking systems to mobile apps.
But in 2019, Oracle changed the rules. They began charging subscription fees for certain versions of the Java Development Kit (JDK) and altered the license terms. Today, using the “wrong” version of Java—or using it in the wrong way—can result in surprise audits and costly licensing bills.
Many companies, unaware of the subtle shift, continued using Java, assuming it was still free. Some are now facing compliance audits and back payments running into six or even seven figures.
How to Protect Your Organization
The lesson is clear: never assume “open source” means free from obligation.
Organizations must:
- Understand the license terms of every software they deploy
- Track which versions of software are in use
- Know when “free” becomes “fee”
At Palisade Compliance, we’ve helped companies navigate exactly these traps—especially when it comes to Oracle Java. We know how software publishers blur the lines between open and paid, and we help clients stay compliant while avoiding unnecessary costs.
Final Word
Open-source software is powerful. But power without governance is risky.
Before deploying or continuing to use open-source software—especially in large enterprise environments—make sure you understand the true cost of “free.”
