It really sucked because I've been learning from O'Reilly books for thirty years. But I've become fundamentally opposed to DRM on media and subscription-only access is the ultimate DRM. I don't have any desire to be locked into their app to access stuff I paid for and be at the whims of their poor UI decisions.
I've also been pretty disappointed with their quality and/or usefulness lately. They seem to just cover stuff in a less technical vague high level way now. Hopefully that's just a sampling error on my part.
