You are not hording them, as you would have to sell the boards to fund new projects to archive. The images you dump are for archiving purposes, and would be stored accordingly.
You are only angry with me, because it makes sense. Bugs would still be fixed as there would be delegation of what code would have to be worked on.
I cannot see a project where 30 people are working on the same problem, each providing the same code. That would be crazy.
People catalog books and put them into an archive. They might scan them for public consumption if they are in the public domain. Why is that so different to arcade roms?
I do not understand why you are being so negative.
