My person, seeking and searching for ways and investigating certain realities, has raised a question in regard of "cast-off" on and Application forum for Android:
Sure unusual question: cast-off apps - “cast-off”- licence and depots It's of course a general matter the works behind that, which needs good investigation and my person encourages all to investigate this matter, discuss and contribute.
To understand a little:
If something is "cast-off" on the street, ownership abounded, one might pick it up and "make it his/her own", use it, without violate the precept of "taking what is not given" without the normal need that it is consciously given by the owner or an assistant of him/her to count as given.
Of course one needs to be as much as possible sure, that it is not just gone lost and the owner still hasn't abound it, or that it is just deposited, ownership not abounded.
And, a very matter in regard of "free", is not a trap, meaning that it is made by the owner as seeming being cast-off and objected to catch those taking on it later with demands.
