Joanna Cabot's An Open Letter to E-Book Retailers: Let’s have a return to common sense is just what you'd hope for from a post with a title like that: three commensensical points about ebooks, licensing and DRM that I generally agree with (though I quibble a little here and there). 1. If your button says "Buy this ebook," then I own it. 2. Ebooks are read by households, not devices or the users to whom they're registered. 3. It's not piracy to share the kids' ebooks you buy with your kids. (Thanks, Dan!)
