Yes, I think those books should be free as well. Material costs I'm ideologically fine with people making some profit off of, however inevitable market forces will cut margins lower and lower, until a point where no, people won't make a profit off of them. The most successful of companies will ironically be the ones that give away the most, because they'll be the only ones that can survive in an extremely skeptical public market. I predict this will either not happen, because citizens vote their governments into being socialist benefactors that provide these services for free, instead of the market (I also predict this will lead to increase government abuse). Or I predict the capitalist market will cater to socialist citizens by providing 0 margin services that maintain their monopoly in order to out compete governments or competitors that reap higher profits.
