Maybe there is a misunderstanding in the services proposed by O'Reilley Media. On their eBooks offer (available via their main website - oreilly.com), They don't put your name or any other info on the purchased eBooks. There are no DRMs and you can get the books in many format. That's the services mentioned in the Forbes article. The "Safari Books Online" is another services with many DRM-like techniques but this was a previous services where O'Reilley Media is member along with other book editors. I used it in the past but that was a pain to use it. I suppose O'Reilly now focus on the first service only as this is the one generating revenue without DRMs or watermarking techniques or additional limitations. I buy much more from their non-DRM offer (it's convenient, low-cost and many formats are available).
