This is certain, but the same argument could be made for Linux. This is simply due to the fact that Linux is truly modular. It is equipped with a clean architecture and does not impose a manner in which programs must be run. But most importantly, the latter is not loaded automatically at start-up, which avoids useless consumption of memory when running a dedicated server. The Web is overflowing with testimonies of free software's proven reliability.
High reliability is also crucial in the domain of embedded information systems equipment.
Here again, we often find Linux. What's more, improvements are made available as soon as a glitch is discovered. But even more so than during initial development, it is during the fine-tuning stage that the multiple interventions characteristic of OSS have the biggest impact on final quality. The problem of technical support can alone put a damper on the zeal for free software. It is generally believed that there is simply no technical support for this type of software.
