thats different.The list is endless, I’ve seen selections code own by one company, re-used and hacked by another company.
It’s typically referred to as clean-room reverse engineering (also known as a clean-room design). In essence, one group studies the target system and writes a specification or functional description,
whilst a completely separate team—who hasn’t seen the original code or designs—implements a new version based solely on that specification.
This approach is often used to avoid copyright infringement claims when recreating or emulating a proprietary product.
