> Thanks to O'Reilly for being clueful enough to sell non-DRM versions.

Did O’Reilly start selling ebooks again? Directly? Several years ago it stopped doing that and pushed the Safari or O’Reilly subscription as the only way to read its catalog of books. I provided feedback at that time, but the policies didn’t change. But I have seen some O’Reilly books in Humble Bundle sales once in a while.

There was also a time when O’Reilly and Apress would have a “deal of the day” every single day, selling ebooks at a much lower price than retail..all DRM free. I haven’t seen those in years.
