Don't be fooled. This initiative is not about #OpenAccess books. It's from publishers and authors who generally don't want OA for books. It's about free events about books (good) and transparency about the book industry (good), but not OA for books.

PS: I can't tell whether the name is a marketing mistake by people unaware that "Open Books" is already a thing, and a thing in tension with what they are doing, or whether it's #OpenWashing.

Marketing teams think long and hard about phrases like this.

That group is run by oligarchs' representatives. It would be hard to believe they aren't aware that "open" books are a threat to their revenue streams and dominance.

They see "open" as a threat, so they will use it in other contexts to weaken the concept.
