Aside:

This is another interesting example of the "convenience" of centralisation of source code control around a single website: github.com.

The author seemingly never has to search competing source code control websites or hardware manufacturer websites. Most everything he references is found on github.com

Pine64 required all nutcracker entries to use github.com

Is it worth pondering that a company founded on the idea of not releasing source code to software users, instead copyrighting it and enforcing copyright through the courts and law enforcement, as a means for selling software (licenses), is now in control of accesss to all this open, freely avaialble source code.
