"Open source" software in proprietary products
FOSS compliance
When developing proprietary software, open source software is often used to avoid "reinventing the wheel". For example, a free JPG library is integrated into proprietary software or the Linux kernel is included in embedded software or firmware. The open source software in question is subject to its own open source license conditions, which must be adhered to. In the event of license violations, third parties can demand injunctive relief and damages, among other things. In the open source sector, however, an even more serious consequence can occur: All of your own software may have to be published free of charge in source code. This is known as the copyleft effect or the "infection" of your own software by the open source license.
