Errata (Please update your article)

1. Coinomi is no longer open source

Coinomi stopped publishing their source code with v 1.6.5 sometime before 1 August 2017.

Before that, on 6 November 2016, Coinomi changed their licence to prevent derivative works, and became
not open source according to the open source definition

2. Jaxx is not completely open source.

Clicking View Source Code on their website shows:

Jaxx's code is now available to view below. This is the full code (minus third party libraries) of our wallet's back end; it does not contain any UI elements.

Emphasis mine.
