Earlier quoted context omitted.
Yes, but that isn't free imho. Can I host a copy on my own website? Can I include the book as part of a course taught at my school? Can I integrate chapters of the book into another book that I may be writing? Making a copy available for reading isn't the same as making it free.
That's not really free though, is it? Because I can't really just start hosting it, claiming to be its author, and have people believe me. (White-labelling). For that to happen, the original authors have to stay anonymous, it has to have much less branding included. So it's not really all that free in my opinion, even with your additions. /s
in other words: your standards are too high. It's free because you don't have to pay for it.
