Page 15 of the complaint is fairly damming. Apparently "Campbells Biology" uses a bear eating a fish + running to explain thermodynamics and even this example appears in their version...
It might possibly be legal, but I feel it shouldn't be.
Similarly (from one page later): a Psych textbook used Brahms to illustrate "Sleep disorders" (the general idea), because he apparently suffered from sleep apnea. The Boundless text apparently also chose Brahms to illustrate "sleep disorders".
Again, at the moment, only half the story is being shared. We look forward to publicizing our side once we can!
But you're the one who publicized it! We're only talking about it because you submitted this one-sided blog post. You shouldn't be surprised that a bunch of message board nerds would actually track the filing down.
What is the law regarding copying the fine-scale structure of a book but rewriting it/redoing the pictures?
It does not in & of itself appear promising for Boundless.
