> it allows someone to take up a project if the original author dies. Sure, in theory. In practice I’ve yet to hear of a worthwhile monograph in mathematics written that way. > The best way to get free access to a for-cost text is to use your library. Not all libraries stock for-cost texts of advanced mathematics. Not all people, including gifted high schoolers, live anywhere close to a library. These are especially true in poorer countries. When people make remarks like yours underprivileged demographics always seem to be forgotten. Anyway, readers can do with the Internet as they like, and sorry if you’re offended.
