Old + Old + Old + New

After reading Old + Old + Old = New my previous understanding of how blurry the lines between copyright infringement and fair use can be.  These webpages feature discussions of copyright tendencies and what, if anything, can be done to improve or change them.  It assures us that not all copyright laws are unjust, but many are, and laws need to first be broken to be fixed.    They express the importance of acknowledging the author for their work when reusing art.  Also, they believe in an art "ecosystem" where all past art should be available to anyone to be reused, stored, and collected.  They view it as kind of a shame if art was made to be kept secret, and so they would like art to be public and shared.
