This was unexpected. They lost me as a customer when they stopped allowing me to download books I bought and I'm in the Kobo (+ BookLore) side now and I am not coming back. I wonder how many books are actually DRM-free and are going to be affected by this change. I suspect relatively few, but I would be happy to be wrong
Since I couldn't refund, I had to pirate the book as epub/pdf from elsewhere. I decided to never again buy anything from Kobo.
