Parent is also saying that virtually nobody does it. This is not true. What I linked is one example, given away for free by an engineer at a prop trading firm and a CS professor. Similar to the linked example, we have excellent books on many technical subjects, available for free. And not because the authors are communists but because they want to share the knowledge or because it helps their broader business.

Comparing number of books released for sale vs for free, is isn't unreasonable to use the phrase "virtually nobody". I would guess less than 1% of books are released free.

That's right. There are lots of free books and still almost all books are not free. That's okay, though. People can write a book and choose what to do with it. What IA tried to do removed that option.
