I use MY kindle serial number on a Calibre plugin that removes DRM on books I BOUGHT, so I can read them on MY own KOBO.
So I don't want DRM enabled on the books I write and get published. Yes, "piracy" is wrong, but the amount of "lost sales" are grossly misrepresented.
I totally support copyright. I totally oppose abusive technology controls on how we consume content.
I'm still not any clearer though, on what the actual "flaws" found in this research actually do, or what they affect.
