Copyright laws need a massive overhaul. Patents are arguably more important to society and they only last 20 years. 70 years after the death of the author is ridiculous. If you can't make a profit off of your photographs after 20 years, you have a problem that can't be addressed through copyright law. The whole purpose of protecting copyright holders and patent holders is to benefit SOCIETY by encouraging the production of new ideas and works. It doesn't benefit society when a man in 2023 can stop the world from publishing photographs taken in 1943 by his father who died in 1993. That only benefits the photographer's son, not society.
