For example, programs from disappeared Ascaron company.

One game development by them:

I did that question because Ascaron company developed games, but went
bankrupt in 2009 and I don’t find current right owners over games developed
by them.
Note: I think which there is free software which before was privative
software, but I don’t know how others get it as free software (I don’t
talk about cases where reverse engineering was necessary).
