Sent this to Support at O'Reilly after reading their (to me, insane) e-mail.
Hi O'Reilly,
Just so you know - you've completely lost a customer. After years - decades really - of a highly dedicated customer (whose friends have written books you have published) you threw it all down the drain in one e-mail.
I will never purchase another book published by O'Reilly, or any company associated with O'Reilly, or associated with O'Reilly himself or any of the executives at O'Reilly. I sure as heck am not going to buy any technical books from O'Reilly by Amazon.
The things I liked from O'Reilly, now gone, are:
1. PDF, ePub and Mobi formats, all DRM free, so I could read them in the ideal format for each device I read them on. And, I have a lot of devices: several Macs and PCs, several iPads, several Kindles (used almost exclusively for fiction as technical works are horrible in non-PDF), several phones of various kinds. I could put both the ePub and PDF into iBooks (not my favorite app, but it does sync) and read the ePub on the subway if I wanted, and the PDF on the desktop and iPad (cause, as I said, ePub is terrible for technical books). I like my fully properly typeset color, indexed PDFs!
2. Buy it once, own it. Did you ever see me subscribe to Safari? No? Ever wonder why not? For the same reason that I don't use Adobe products anymore except Lightroom (which is still a purchase not a subscription), and why I dropped JetBrains when they moved to their subscription model and then re-joined them when they went to "Subscription + keep your start of subscription version forever". I don't rent stuff. I buy it and own it. Plain and simple.
I'm glad that there are other publishers out there like Pragmatic Press and Apress that have been publishing good content, because you just lost a highly dedicated customer who always shopped O'Reilly first even for non-O'Reilly books. Congratulations, and shame on you.
