I dislike 'source available' - We only have to look at new pipe and pipe pipe to see why... New pipe doesn't agree with sponsor block so they don't include it... pipe pipe just follows new-pipe and includes sponsorblock... So users have the option of new pipe, or pipe pipe - depending on the experience they want - all thanks to open source.
In the source available word we can't get someone to make a grayjay fork with light mode (instead of dark mode,, so brightjay)... because while they can see the source they can't fork the source... This means that all the friction that people would either solve themselves in a push request or in a fork... just get dropped on the feat of grayjay developers as issues and the ecosystem suffers with sloth or abscense
