Heavy fee for renting digital textbooks

Today's US college students are trapped in a system which automatically forces each student to pay a heavy fee for renting digital textbooks.

These can only be read with nonfree software, which makes them fundamentally unjust. And the rental expires in a year.

I would resent being compelled to pay so much, but the big injustice would lie in running those nonfree programs. A student could perhaps avoid that injustice by photographing all the pages of someone else's copy off a screen.
