Despite the statement in the title, there are no contraditions with open access books, and Joseph Esposito's presentation of this story is unsurprisingly skewed. Nonetheless, it's a story worth telling. Open access publisher Knowledge Unlatched has recently pivoted to a commercial biusiness model. Part of this is the (beta) launch of a centralized Open Research Library, described here. It aggregates open access books and puts them into a closed and commercial viewer and charges money for additional services. Unsurprisingly, there were objections. Commercial OA publishers have expressed discomfort. None of this is surprising; it was predicted long ago, and we've seen it play out before. That's why I use a non-commercial Creative Commons license.
