Why don’t application developers who have abandoned their development make the code they don’t need open source? - Lemmy Today

There are many closed source applications that have been removed from the Google Play catalog for various reasons. Often this reason is the cessation of further development and maintenance of the application. Why don’t these people make the code open to everyone if they don’t need it anymore? This could bring great benefits to all people, but everything that was once created simply disappears.

Additional question: wouldn’t it be cool to have a place where you can only get open source stuff? Obviously there needs to be more to it than this fact i presume but its a start.
