FOSS is about the trade-off of maintain-ability, and ethics. (Maintain-ability as in paying for only what you need for a project, to be maintained over time. (aka the deficit) If there's two sides of this coin; Free Software would have no trade-off so have little maintain-ability, and tiny scaling, but have full rights to do whatever you want with the software. Or Proprietary Software which has no ethics but has easy maintain-ability, and can quickly scale up with profits earned. Open-Source Software is the middle ground with less monetization options than proprietary software, it trades quick growth for ethics that the everyman can benefit from, without smothering the ability to scale with slowly earned profits.
