> My employer (Wikimedia, which is a non-profit) has been running all our server infra on pure open source for many years, for very principled reasons Curious how deep does it go? Do you only use firmware in server which has open source code. Do you require all drivers to be open source? > It should be possible to run large-scale important things on pure open source. It is definitely possible. With enough developer time, you could create copy of any software. Every paid or open core software runs on the philosophy that it is cheaper to pay them rather than to build them. Which brings to the core issue, developer time is not free or cheap. The fact is that software quality and reliability is dependent on the money that the software has means paid software quality in general should be higher. While wikimedia could get enough money through donation, no one donates to open source projects that could be counted in full time developer salary, likely not even wikipedia(correct me if wrong).
