>The relationship with commercial vendors isn’t always healthy, but many major OSS projects are supported to a significant extent.
Almost always the so called "community" supporting a OSS project is an employee of a commercial vendor who is only interested as long as he is assigned to the project or task.
The solution is to have a full time owners and maintainers for all the critical projects and the government has to foot the bill. The govt can setup a division to identify such projects.
