I'm trying to rediscover a book about copyright I once read. The book's cover was the iconic copyright C and a vertical strip motive. It is/was freely distributed as a digital edition.
The book discusses:
the flaws with the current copyright system by drawing a graph where 4 different pressures on the law have forced it to become untenable.
It elaborates on this by showing similarly untenable cases in the past where farmers where suing airplane companies because they caused their livestock to die and they owned the airspace above their land.
The law of land ownership assumed the right stretched down to the core forever and towards the sky forever.
even though they are holding dead chickens in their hands and it's clearly the planes, there was nothing they could do. The public good was more important than a few farmers
paraphrased quote from the book
It also elaborates on modern practices like piracy and software.
