Language works this way. Once you master the standards, anybody can coin a word they can put into the language. It's not really an ownership issue. There can be standards that are open and that are actually owned by a company or an institution. Sometimes networks can be privately owned and yet be open, in the sense of making it easy for anybody to make a significant contribution to the enterprise.
Many people believe open source is less profitable than proprietary, closed systems.
In the short term, that may be the case. If somebody has an innovation that is truly significant and they have a proprietary system, then they can have a short-term opportunity to produce income. But it will not keep up with the general growth of an open system. Inc. All rights reserved.
