Actually there are relatively few real (TM) open source projects driven by the community, at least if you look at important projects. Many open source projects are just commercial projects driven mainly by a single company. Look for example at Redis, MongoDB, MySQL, and Elasticsearch. They follow exactly the model described in the article. Technologies like these could have been developed by a community, too, but it…
If we look at the Top 10 programming languages, I think only Ruby is community driven that has very little cooperate backing. All the other languages are driven by one (Apple;Swift), or multiple, (Javascript, Java) cooperate sponsors. I think the balance is hard, you will need lots of resources from Documentation, VM expertise, Library, etc.
Of these, Javascript (w3), Python (Python Foundation), CSS (w3), C++ (ISO), Ruby (community), C (ISO), Shell (Posix), R (community), Perl (community), and Haskell (community) are not bound to a single company.
