A famous stained-glass window in a church in my home town was heavily censored (i.e. publishing photographs of it resulted in legal threats, fair use or not) because the estate of the late artist who created it vigorously enforced his copyright. High-resolution photographs were available for free of every stained-glass window on the church website, except for this one. At times there were even talks about covering it up physically because of claims about public display licensing issues. The artist in question likely didn't see any of this coming during his lifetime. Being granted exclusive protections during your lifetime or for a reasonable period of time after the creation of a work is defensible. De facto perpetual protections afforded to the artist's grandchildren (or great^n-grandchildren), not so much.
