Why can anyone read and modify the code of some software, like Linux or Firefox?
Show answer & explanation
Answer: Its source code is released publicly
Its source code is released publicly ✓ — Correct! Software like Linux and Firefox is open source, meaning its source code is released publicly for anyone to read, audit, and modify. That openness lets communities spot problems, contribute fixes, and adapt the software to their own needs, which is why these projects often improve quickly. It doesn't mean the code is flawless, and it doesn't mean the software is always free, since some open source projects charge for support or extra features.
It has no security bugs — Wrong. Open source doesn't mean bug-free. It means the code is public, so anyone can review it and contribute fixes, which often improves quality over time but never guarantees zero security bugs.
It never costs money to use — Wrong. Open source means the code is accessible, not necessarily free. Some projects charge for support or extra features, and many are free, but 'open source' refers to code availability.
