Have had Safari Books Online for about a year now, got it 50% off last August, love it. There have been several books I started reading in SBO and then ordered physical copies on Amazon. Never even occurred to me to order the books from Safari directly. The books I order are about broad topics and themes (Designing Data-Intensive Applications, Enterprise IoT, etc.). Rarely would I order a book about a specific Language or Framework, they have a limited shelf-life, but I'll absolutely reference the online versions to grab the info I need (more valuable format, can have open on monitor, search, etc.). Their process for alerting authors of this change may not have been great, but it seems like a smart business decision (assuming my use case if fairly typical).
