Open source means surrendering your monopoly over commercial exploitation

Participating in open source requires surrendering your monopoly over commercial exploitation of your software. The Open Source Definition and Free Software Foundation both explicitly require that anyone — including competitors like Amazon or Google — can monetize FOSS code. This is a fundamental, non-negotiable aspect of FOSS philosophy that many companies struggle to accept. In exchange, the community contributes improvements back, creating broader value than any single organization could alone. Copyleft licenses like the GPL allow authors to ensure others share their improvements, but cannot restrict commercial use. Companies consuming or producing FOSS must understand these obligations and build business models that work within this reality.
