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.
Because I don’t want people seeing my terrible code
Isn’t there bad code in the free software world?
I remember the news when Dwango company decided to open source the Toonz program. On one of the forums I read a lot of criticism about the quality of their code.
But no one will deny that this is a useful program for artists, even if the program code is not very good.
